RSPLOT V1.1 User's Guide Copyright (c) 1988, By Bob Silliker All Rights Reserved THIS SOFTWARE IS FREEWARE AND IS NOT TO BE SOLD IN ANY FORM V1.1 RSPLOT User's Guide 1 1.0 Introduction Rsplot is a general purpose data plotting program that will work in both MEDIUM and HI resolution modes on the ST series of computers. The program takes white space separated columns of data stored in ascii files and plots it under user control. The user selects which columns of data to plot and has complete control over the axis scales, marking and labelling. Plots generated in one resolution can be viewed in the other resolution. The program provides for independant Linear or Log10 axis scaling for each axis. Linear scaling can be 1, 2 or 4 quadrants and Log10 scaling is 1 quadrant. The program was written primarily for use with output files from the OPUS spreadsheet program that was published in the September 1988 issue of the ST Log magazine (I have no connection with ST Log magazine except that I purchased a few magazines). However, it can be used with any data file that has columns of numerical ascii data. This manual was generated using PROFF V1.0 by Ozan S. Yigit & Steven Tress. V1.1 RSPLOT User's Guide 2 2.0 About the program Version 1.1 has a fix made to the parsing of the command line to be compatible with Mark Williams Shell. Version 1.0 is the first distribution of RSPLOT. There are no known bugs at this time. 2.1 Applications The program supports 10 graphs per application (an application being one RSPLOT configuration file). Each graph can contain up to 10 plots with each plot having it's own set of attributes (lines, bars, markers etc). It is possible to mix the types of plots on each graph. The plot types are lines, lines with markers, markers, group bars, stacked bars and overlayed bars. The RSPLOT configuration file has the extension .PLT and when creating or renaming applications the program will force the extension, ignoring anything you put in. 2.2 Axis Each graph has one X axis and two Y (a left and a right). Each plot is associated with a Y axis. This makes is possible to view two sets of data that have a common X axis but vary widely in Y values or have different units of measure (such as current and temperature). Each axis can optionally have an axis line, axis numbering, tic marks, grid lines and a label. Each axis can also have either a linear scale or a log10 scale. 2.3 User Lines Each graph has 4 user defined lines associated with each axis. Each line is given an axis position and a string of text that will be printed on the line. The X axis lines are vertical and the Y axis lines are horizontal. The labels for the X lines are display centered at the top of the line. The labels for the left Y axis lines are displayed over the line on the left of the screen and the labels for the right Y axis lines are displyed over the line on the right of the screen. 2.4 Data Files The user can set up 10 data files per application. Each file can contain upto 65530 lines of data. Each line can be a maximum of 640 characters or 64 columns. Anything after either of these two limits will be ignored. A line is defined by anything upto and including V1.1 RSPLOT User's Guide 3 the newline character (0x0A). Anything after the newline character is part of the next line. The program will ignore any non-printable ascii characters and lines that do not contain any numbers. When setting up a plot you select the two columns (1 based) that will be used for X and Y values. If the X column is 0 then the program will generate it's own X values. These values start at X value 1 for the first Y value and increment by the X value by Y for each Y value. This makes it possible to view a single column of data. 2.5 Data Filtering For each plot there are X and Y minimum and maximum setpoint values. Initially these values are set to nothing and the filter is disabled. When legal values are set up and the filter is enabled the program will check each X and Y value against the appropriate filter values and will plot points that fall within the setpoints inclusive (that means if the X setpoints are 10 to 100 and the Y setpoints are 0 to 1 then points will be plotted where X >= 10 and X <= 100 and Y >= 0 and Y <= 1). 2.6 Rotating Data A new feature to the program has been added that allows rotating the data loaded from the data file such that rows and columns are swapped. This provides a means of viewing data by rows. When viewing a data, in the data window, that has been rotated the file rows are now data columns and file columns are now data rows. The number of rows and columns that can be rotated this way is limited to 64 of either and the program will limit this when loading the data file. If you have a data file that has more that 64 rows or columns that you want rotated then you will have to write a conversion utility to rotate the data before using it with RSPLOT. 2.7 Memory Usage All data for a data file is memory resident and are stored as doubles (that's eight bytes per value). If you have alot of large data files you may run into memory problems. There are not many solutions to this problem at this time. One solution is to try to keeping the organization of the data files such that there are no unused columns. You can also try the usual 'remove' all desk accessories' trick. The only other solution is to break the data file into parts and create a separate configuration file for each data file (YUK!). 2.8 Hard Copy The program currently will output graphs into DEGAS compatible files V1.1 RSPLOT User's Guide 4 or print graphs onto EPSON compatible printers. The driver used to make hardcopies is the same driver that the ALT-HELP sequence uses. So if you can do screen dumps with ALT-HELP then you can use the Hardcopy menu entry to print graphs. If you have access to DEGAS you can use the DEGAS printer drivers or you can design your own by obtaining a copy of the DEGAS printer driver tool kit that Tom Hudson wrote and which appeared in START magazine Spring 1987 Volume 1 number 4 (I have no connection with either Tom Hudson or START magazine, except that I am a, somewhat, satisfied customer). 3.0 Usage rsplot.ttp [graph-configuration-file-path] As the command line indicates the program takes an optional argument that is a path to a graph configuration file which will be loaded and displayed at program startup. If you don't specify a graph application file on the command line, or the graph application file does not exist, the program will display a blank screen with the menu bar. 3.1 Create the application To start a new graph application select the New menu option in the File Menu. The program will open the graph window and create a graph with the default graph attributes and axis scales. At this point there are no data files loaded or plots enabled. 3.2 Set up the data files To set up the data files select the Data Setup menu option in the Graph menu. This will display a dialog contains text editable fields for 10 data files. Enter the data file paths into the paths fields then select which data files are to be loaded. Only data files with the enable arrow highlighted will be loaded. If you want to rotate a data file then select the rotate arrow for that file. Select the [ OK ] exit button and the program will attempt to open the selected data files. If a file can't be opened then the program will display the error dialog for that file when you close the dialog. 3.3 Set up the axis scales To set up the axis scales select the Axis Setup menu option in the Attr menu. The axis scale dialog will be displayed. Set up the XMIN, XMAX and Y1MIN and Y1MAX scale values. If you will be plotting two plots on the same graph then set up the Y2MIN and Y2MAX values as well. If you want an axis to have a LOG10 scale then highlight the [ LOG ] button for that axis. Otherwise the axis scales will be linear. V1.1 RSPLOT User's Guide 5 Now it is time to decide how the axis numbers will be displayed. You have a choice of: AUTO Let the program chose how to number the axis. The program does a reasonable job of axis numbering. STEP Display numbers by a fixed increment from the XMIN value. This requires the STEP value to be set up. DIV Display a fixed number of numbers. This requires the DIV value to be set up. If desired set the number of decimal places that the axis numbers will be displayed to bu filling in the DECIMALS value. This dialog is explained in section 5.2. 3.4 Set up the axis attributes If the default axis attributes are not what you want on your graph then select the Graph Attr menu option in the Attr menu. A dialog will be displayed that contains enable flags for the graph attributes. Each axis has it's own set of attribute flags. To enable an attribute for an axis highlight the axis name associated with the attribute. This dialog is explained in section 5.3. 3.5 Set up the plots At this time the graph application has been created, the data files have been loaded and the axis scales and attibutes have been set up. To view a plot select the Plot Attr menu entry in the Attr menu. A dialog will be displayed that contains all of the plot attributes. Set up the file number, x and y columns, select the type of plot (lines, markers, bars ...) and the style (line style, marker type, fill pattern), highlight the [ ENABLE ] button and select the [ OK ] button. The dialog will close and the screen will be redrawn. Any data points that fall within the X and Y limits set for the graph will be displayed. If you want more than one plot on the graph then select the Plot Attr menu option in the Attr menu. The dialog for the last plot displayed in the dialog will be re-displayed. Select the [ Next ] or [ Prev ] buttons until the desired plot number appears. Set up the new plot type and enable the plot. Close the dialog with [ OK ] and the screen will be redrawn. V1.1 RSPLOT User's Guide 6 This dialog is explained in section 5.1. 3.6 Add a graph To add a graph select the Graph Setup menu option in the Graph menu. This will display a dialog that contains the first graph title and an enable flag for 10 graphs. To add a new graph enter a graph title (optional) and highlight the enable arrow for the new graph. Select the [ OK ] exit button. The new graph will not be shown yet (unless it is the only graph). Using the Next Graph and Prev Graph menu options in the Graph dialog page through the graphs until the new graph is displayed. Follow steps 3.3 and 3.4 above to set up the plots and axis scales. 4.0 Menu Entries 4.1 Menu Layout -------------------------------------------------------------------- File Graph Attr User Output Misc -------------------------------------------------------------------- |New |Graph Setup|Plot Attr |X Numbering |Hardcopy|Blowup | |Open |Data Setup |Axis Scales |Y1 Numbering|--------|Reduce | |-------|Plot Setup |Axis Attr |Y2 Numbering|Degas |Value | |Save |-----------|------------|------------|--------|-----------| |Save As|Next Graph |Graph Legend|X Lines | |Color | |Close |Prev Graph |------------|Y1 Lines | ----------- |-------|-----------|Graph Titles|Y2 Lines | |Quit |View Data |Graph Labels|------------ ------- ----------- ------------ 4.2 File Menu The file menu contains menu entries that control the creating, opening, saving and closing of graph applications, and program termination. New Start a new graph application. The program will enable the first graph. The user must set up the data files, plot attibutes, axis scales, and axis attributes. Open Open an existing graph application. There can be only one graph application open at a time. Save Store the graph application into the existing graph application file. Only the graphs that are enabled will be saved. If you disable a graph then save and quit the graph V1.1 RSPLOT User's Guide 7 that was disabled will not be saved in the file. This menu entry is only available if you have opened a graph application or if you have created a new graph application and have saved it using the Save As menu option. Save As Save the graph application into a new graph application file. This is used when you want to save a new graph application or rename an existing one. Close Close the graph application. If you have made changes to the graph application and not save them you will be prompted to SAVE then CLOSE, CLOSE or CANCEL. Quit Terminate the rsplot program and return to the shell or desktop that started the execution of rsplot. If you have a graph application open and you have made changes and not saved them you will be prompted tp SAVE then QUIT, QUIT or CANCEL. 4.3 Graph Menu The graph menu contains menu entries that give the user limited access to all the graphs, data files, and plots for the current graph. Graph Setup Displays an editable dialog that contains the first title line and the enable flag for each graph. Only graphs with their enable flag highlighted are available for viewing. Plot Setup Displays an editable dialog that contains plot information for the current graph. There are utpto 10 plots per graph. The dialog contains the plot title that is displayed in the legend (when the legend is enabled) the file number, X column, Y column, Y axis association, and plot enable flag. Only plots that have their enable flag highlighted will be displayed on the graph. Data Setup Displays a dialog that contains the paths to the data and a flag that indicates whether the data for the file should be loaded. Only data files that have their load flag highlighted will be available for plotting. Next Graph Display the next graph. This menu entry will be disabled if there is only one graph enabled. V1.1 RSPLOT User's Guide 8 Prev Graph Display the previous graph. This menu entry will be disabled when there is only one graph enabled. View Data Display the data loaded for any data file that has been loaded. When selected this menu entry displays a dialog that shows a 4 column by 14 line window of the current data file. The user can position the window anywhere in the data file using the arrow buttons. 4.4 Attr Menu The attr menu contains various menu options that enable to user to set graph and plot attributes for the current graph. Plot Attr Display the plot attribute dialog and allow the user to change plot attributes. You can change the plot name, data file number, X axis column, Y axis column, Y axis association, bar width, stack number, plot type, marker type, line style, and fill pattern. Axis Scales Display the axis scale dialog and allow the user to set the X, Y1 and Y2 axis scales, how the axis numbering will be generated (either auto, step or division), and whether Y axis labels are left or right justified. Axis Attr Display the axis attribute dialog and allow the user to enable/disable labels, numbering, lines, tics, origin line, grid lines, and no negative values for each axis. Graph Legend Display the graph legend. When this menu entry is checked the program will display the graph legend in the upper left corner of the graph. Only those plots that are enabled and have a plot name will be displayed in the legend. Graph Titles Display an editable dialog showing the three graph titles for the current graph. The three graph titles are shown centered at the top of the graph in the order specified in the dialog (the first at the top, the second under it, ...). Graph Labels Display an editable dialog showing the three graph axis labels. The X axis label is displayed centered at the bottom of the graph under the X axis labelling. The Y1 axis label is displayed centered (vertically) on the left side of the graph and Y1 axis labelling. The Y2 axis label is displayed V1.1 RSPLOT User's Guide 9 centered on the on right side of the graph and Y2 axis labelling. 4.4 User Menu The user menu contains menu entries that allow the user to change the labelling of an axis from numeric to a ascii strings and add lines to each axis at fixed points. X Numbering Y1 Numbering Y2 Numbering Each dialog contains 12 value-string pairs and and enable button. When the enable button is highlighted and the program draws the axis numbering (for the axis with the enable highlighted) the axis numbering will be replaced with these 12 strings. If you want the tic marks to line up with the axis strings then you must use the Axis Scales menu option to set the axis min, max and step values (step enabled) to the required values. X Lines Add vertical lines associated with the X axis. Y1 Lines Add horizontal lines associtaed with the left Y axis. Y2 Lines Add horizontal lines associated with the right Y axis. 4.5 Output Menu This output menu contains menu entries to create hardcopies of the graphs or store the graph into a file for processing by other programs. Hardcopy Displays an editable dialog with 1 button for each graph which the user selects to be output to an EPSON compatible printer. When the user selects the hardcopy button the screen will clear and the first graph selected for hardcopy will be displayed. At this point the user is presented with a dialog indicating that the printer be set up. You should adjust the paper in the printer at the desired position and select the [ EPSON HARDCOPY ] button. The program will pause with this dialog before plotting each graph. With the correct adjustment of the printer the program will plot 2 graphs per page. Degas Output the current graph into a degas formatted file. The program will display the standard file selector dialog and when the user selects [ OK ] the program will create the V1.1 RSPLOT User's Guide 10 degas file. 4.6 Misc Menu The misc menu contains menu entries that allow changing the view of a graph and control there drawing of the graphs. You can also set the overall screen colors. Blowup, Reduce and Value share the mouse pointer and the left mouse button. Only one can be checked at any one time. Blowup When this is checked the user can blowup a portion of the graph (making it larger therefore showing less of the graph). Using the mouse pointer and the left mouse button the user draws a box on the screen and, when the mouse button is release, the program will rescale the graph to show only the area in the box. There is no undo for this operation (other than resetting the axis scales using the Axis Scales menu entry). Reduce When this is checked the user can reduce a portion of the graph (make it smaller therfore showing more of the graph). Using the mouse pointer and the left mouse button the user draws a box on the screen and, when the mouse button is released, the program will set the axis scales so that the information that is currently on the screen is now inside the box. It takes a little getting used to. There is no undo for this operation (other than resetting the axis scales using the Axis Scales menu entry). Value Enable the mouse to be used as a pointer to determine the values of points in the plotting area. When this menu entry is checked, and the user presses the left mouse button while the mouse is in the plotting area, the program will display the X, Y1 and Y2 values the of the mouse pointer in a dialog. Color Displays a dialog that allows the user to set the screen colors. 5.0 Important Dialogs 5.1 Plot Attributes Dialog PLOT # The current plot number. This is an uneditable field except V1.1 RSPLOT User's Guide 11 that the user can use the NEXT and PREV buttons to change the current plot. DATA FILE The number of the data file that the data will be taken from. The number is found on the left side of the Data Setup dialog. If the data file has not been enabled then the plot will not be shown. X COLUMN The column number (1 based) in the data file where the data for the X axis will be taken from. If the column does not exist or does not have any numeric values in it, the plot will not be shown. If the X column is set to 0 then the program will generate it's own X column starting at 1 for the first data point and incrementing by one for each row in the Y column. Blank fields in the Y column get a number. This allows plotting a single column of data without having to create a column of sequential numbers. A nice idea. Too bad it wasn't mine. Y COLUMN The column number (1 based) in the data file where the data for the Y axis will be taken from. If the column does not exist or does not have any numeric values in it, the plot will not be shown. Y AXIS The Y axis that the plot will be associated with. Legal values are 1 - left side or 2 - right side. The two Y axis can be scaled independantly and so it is possible to view two sets of data, that have a common X axis but whose Y values are orders of magnitude apart, on the same graph. PLOT NAME The name of the plot. This string will be placed in the Graph Legend across the marker type, line style or fill pattern when the Legend is enabled. BAR WIDTH The width of the bars when bars are displayed. STACK # The stack number when stacked bars are being plotted. This is used when you are plotting two or more separate sets of stacked bars on the same graph. PLOT TYPE Set the plot type. The user has the option of selecting: LINES Draw lines between points. To prevent lines from V1.1 RSPLOT User's Guide 12 being drawn backwards (right to left) the data should be sorted ascending by the X column. MARKS Draw a marker at each point. LINES AND MARKS Draw lines and markers at each point. GROUP BAR Draw bars using bar width. When used with more that one plot the bars are placed side by side where the points match on the X axis. STACK BAR Draw stacked bars using bar width. When used with more than one plot the bars are stacked on top of each other where points match on the X axis and the STACK # for the plots are the same. OVERLAY BAR Draw overlay bars using bar width. When used with more than one plot the bars will overlap (sometimes hiding other bars). NOTE: Plotting multiple plots with bars works best when the X axis is common to all the plots. This is really a must when stacking bars. MARKER TYPE Set the marker used when MARKS are enabled. LINE STYLE Set the line style used when LINES are enabled. FILL PATTERN Set the fill pattern when BARS are enable. FILTER Displays the filter set up dialog on top of the plot attribute dialog. Each plot can reject data that fall out of X and Y ranges. This dialog provides a means of setting minimum and maximum X and Y values. The filter has to be enabled in order to reject data. ENABLE Enable the plot for display. This must be highlighted in order to show a plot. OK Store the changes made to the current plot and close the dialog. V1.1 RSPLOT User's Guide 13 NEXT Display the attributes for the next plot. If the current plot is 10 then the next plot will be plot 1. The changes made to the current plot are stored as if the [ OK ] button was selected. PREV Display the attributes for the previous plot If the current plot is 1 then the previos plot will be 10. The changes made to the current plot are stored as if the [ OK ] button was selected. CANCEL Cancel the changes made to the current plot and close the dialog. If the user has made changes to a number of plots using NEXT and PREV the changes made to the other plots will not be cancelled. 5.2 Graph Scales Dialog GRAPH # The current graph number. This is an uneditable field. X MIN Y1 MIN Y2 MIN The minimum limit for the the specified axis. X MAX Y1 MAX Y2 MAX The maximum limit for the specified axis. This must be larger than the MIN limit for the axis. If it is not then the MIN and MAX limits will be swapped. If the limits are the same then the program will keep the old limits. X STEP Y1 STEP Y2 STEP The step value for axis numbering. Axis numbers will occur at each N * STEP + MIN position. If STEP is blank, zero or illegal then the axis numbering will not be shown. X DIV Y1 DIV Y2 DIV The number of divisions to divide the axis range into for axis numbering. Axis number will appear at each N * (MAX - MIN)/DIV + MIN position. If DIV is blank, zero or illegal then the axis numbering will not be shown. LOG Axis scale is logarithmic. All axis scales must be > 0.0. If you try to set the minimum to <= 0.0 the program will use V1.1 RSPLOT User's Guide 14 1.0. You can, however, set the axis scales to something like .001 -> 1000. Which will span 6 decades. AUTO Enable auto numbering of the axis. The program tries to keep the axis numbering to a reasonable number of digits. It's not perfect. When AUTO is enabled the program will exceed the number of decimal places set in the DECIMALS field below for the specified axis in order to show a significant number if decimal places. STEP Enable numbering the axis by the fixed STEP value. When this option is used for a LOG scale the value is a log10 step value (that is, if STEP is 1.0 the steps will be 1, 10, 100, ...). DIV Enable numbering the axis by dividing the axis range by the number of divisions set by DIV. DECIMAL PLACES The number of decimal places to print the axis values to. RIGHT JUSTIFY When displaying the axis numbering make all of the values line up on the right side. This applys to the Y1 and Y2 axis only. OK Store the changes made and close the dialog. CANCEL Close the dialog and do not save any changes. 5.3 Graph Attribute Dialog The Graph Attribute dialog is used to control what is displayed on the graph that is common to all the plots on the graph. Optionally, a graph can have axis labels, axis numbering, axis tics, an origin line, grid lines and contain no negative values. GRAPH # The current graph number. This is an uneditable field. AXIS LABELS Enable axis labels for each axis X, Y1 and Y2. AXIS NUMBERS Enable axis numbering for each axis X, Y1 and Y2. AXIS LINES V1.1 RSPLOT User's Guide 15 Enable axis lines for each axis X, Y1 and Y2. AXIS TICS Enable axis tic marks for each axis X, Y1, Y2. ORIGIN LINE Enable axis origin line (0.0) for each axis X, Y1 and Y2. AXIS GRID Enable grid lines for each axis X, Y1 and Y2. Grid lines appear at each tic mark. NO NEGATIVE Disable negative values for each axis X, Y1 and Y2. If an axis is currently negative then MIN will be set to 0.0. Any attempt to set the axis MIN < 0.0 will fail. OK Store the changed made and close the dialog. CANCEL Close the dialog without storing the changes made. 5.4 Plot Shift Dialog A the Plot Shift dialog is displayed along the bottom of the screen when a graph application is open. This dialog has four bottons that enable panning through the data along the X axis. +4 SHIFT Clicking one either the left or right shift button will cause the X axis scales to be moved down or up one axis tic. If the tic marks are 10 apart then 10 will be subtracted/added from/to XMIN and XMAX. The screen will be redrawn to show the data. These buttons will not work if the axis scales are not set up correctly. PAGE Clicking one either the left or right page button will cause the X axis scales to be moved down or up one full screen. If the difference from XMIN to XMAX is 100 then 100 will be subtracted/added from/to XMIN and XMAX. The screen will be redrawn to show the new data. These buttons will not work if the axis scales are not set up correctly. 6.0 Notes If a plot is enabled and the data file is not loaded then the plot will be disabled. To display the plot you will have to load the data file and then re-enable the plot. V1.1 RSPLOT User's Guide 16 When plotting stacked bars the program uses additional memory space to hold the current stack heights. If you have little free memory available the program will give an out of memory error dialog when plotting. The axis numbers will not be displayed if the axis scales are not set up correctly. That is, if MIN and/or MAX is blank. It is possible to get confused axis numbering by specifying axis numbering by step and choosing a small step value or by specifying axis numbering by divisions and specifying a large number of divisions. This can also be accomplished by using alot of decimal places in the axis numbering. The program will only draw the first axis number when the distance between the numbers is less than or equal to 8 pixels. This prevents long pauses while the program draws the axis numbering that would otherwise be a confused mess. 7.0 Warnings Beware of columns of data that are missing some values. A file that looks reasonable to the user might give a confused plot because a column is missing data values. E.G. 1 50 35 2 60 45 3 55 4 70 65 When the user plots this file (which, to most humans, is missing a value in column #2 the program will read in the data file like this: 1 50 35 2 60 45 3 55 4 70 65 Which is missing a value in column #3. This is caused by the fact that a column is defined as any amount of whitespace followed by any amount of non-whitespace followed by, but not including, any amount of whitespace (whitespace here is any character that is <= 0x20 or > 0x7F). If you must have missing data in your columns you can use any non-numeric non-whitespace string to fill in the column position. Such as: 1 50 35 2 60 45 3 ** 55 4 70 65 V1.1 RSPLOT User's Guide 17 The ** in row 3 column 2 will preserve the alignment of the data but will not cause a point to be drawn for row three when column 2 is used for plotting. 8.0 Future Enhancements These are some of the things that I would like to change if I decide to produce an update to the program. There is no gaurantee that these or any other improvements will be made available. It would be nice if the user could select the type of data storage on a per file basis and maybe even a per column basis. This would greatly reduce the memory requirements for some applications. I would like to see integer, long integer, float and double. Remove the limit on the number of graphs per application. Add some data analysis features. Simple stats, linear regression, sorting. Add the ability to edit the data window. When the X column is 0 the program generates a column starting at 1 and incrementing for each data point in the Y column. It would be nice to set the starting value and increment. 9.0 Bug Reporting Should you find a bug or would like to suggest an improvement please e-mail me at: bobs@moliman.molienergy.bc.ca or ...!uunet!van-bc!resrch!moliman!bobs Table Of Contents RSPLOT V1.0 1.0 Introduction.................................................... 1 2.0 About the program............................................... 2 2.1 Applications................................................. 2 2.2 Axis......................................................... 2 2.3 User Lines................................................... 2 2.4 Data Files................................................... 2 2.5 Data Filtering............................................... 3 2.6 Rotating Data................................................ 3 2.7 Memory Usage................................................. 3 2.8 Hard Copy.................................................... 3 3.0 Usage........................................................... 4 3.1 Create the application....................................... 4 3.2 Set up the data files........................................ 4 3.3 Set up the axis scales....................................... 4 3.4 Set up the axis attributes................................... 5 3.5 Set up the plots............................................. 5 3.6 Add a graph.................................................. 6 4.0 Menu Entries.................................................... 6 4.1 Menu Layout.................................................. 6 4.2 File Menu.................................................... 6 New........................................................... 6 Open.......................................................... 6 Save.......................................................... 6 Save As....................................................... 7 Close......................................................... 7 Quit.......................................................... 7 4.3 Graph Menu................................................... 7 Graph Setup................................................... 7 Plot Setup.................................................... 7 - 1 - Data Setup.................................................... 7 Next Graph.................................................... 7 Prev Graph.................................................... 7 View Data..................................................... 8 4.4 Attr Menu.................................................... 8 Plot Attr..................................................... 8 Axis Scales................................................... 8 Axis Attr..................................................... 8 Graph Legend.................................................. 8 Graph Titles.................................................. 8 Graph Labels.................................................. 8 4.4 User Menu.................................................... 9 X Numbering................................................... 9 Y1 Numbering.................................................. 9 Y2 Numbering.................................................. 9 X Lines....................................................... 9 Y1 Lines...................................................... 9 Y2 Lines...................................................... 9 4.5 Output Menu.................................................. 9 Hardcopy...................................................... 9 Degas......................................................... 9 4.6 Misc Menu.................................................... 10 Blowup........................................................ 10 Reduce........................................................ 10 Value......................................................... 10 5.0 Important Dialogs............................................... 10 5.1 Plot Attributes Dialog....................................... 10 5.2 Graph Scales Dialog.......................................... 13 5.3 Graph Attribute Dialog....................................... 14 5.4 Plot Shift Dialog............................................ 15 6.0 Notes........................................................... 15 7.0 Warnings........................................................ 16 8.0 Future Enhancements ............................................ 17 9.0 Bug Reporting................................................... 17 - 2 -
