.                      GRAPHTIME-II Plotter Drivers

Plotter types supported:  All A3/A4 plotters with HP7400 series HP-GL
capability.

Capabilities:
 Two plotter modules are available; one for the DRAW program and one for the
 GRAPH program.
 The GRAPH plotter driver currently outputs all graph types with the exception
 of the Area, Gantt and 3-D Block chart.
 The DRAW plotter driver outputs all drawing elements except pattern fill for
 irregular areas and fonts 1-7. (Pattern fill is available for frames, dots
 and circles.)

Connecting plotter:

 The Plotter is assumed to be connected to printer port: LPT1:. If a serial
 port is used then redirect output by using startup command: GTC1 for serial
 port COM1, or GTC2 for serial port COM2. (Instead of GT). Baud rate
 currently =4800.
 (Modify the GTC1.BAT or GTC2.BAT files to change serial port parameters.
 Use any text editor or the GRAPHTIME text editor.)

 To load plotter driver, startup GRAPHTIME-II in the normal way and select
 DRAW or GRAPH. Then place the Plotter Drivers (on PLOTTER disk #3) in drive
 A: (If on hard disk (C:), the plotter drivers should already be available).

 From GRAPH program: To select GRAPH plotter driver enter: DP [Draw Plotter]
 From DRAW program: To select DRAW plotter driver enter:  GP [Graph Plotter]

Set Up [PS]  (This should be selected before any other plotter command).
 Output selection:
 Graph: Outputs HPGL direct to plotter or to a file (name.GTG).
 Printer: The HPGL file created can be output to an EPSON/IBM graphics printer
 in higher resolution than a screen-print.
 External: Output HPGL file for transfer to other systems. e.g. Ventura

 Paper size can be A3 or A4. Each graph can be scaled in the range 1 to 100.

 Headings and free-text can be output in 9 sizes and 8 colours.

 Number of Pens: 1 to 8
     Colours: 1:Black,  2:Green,  3:Red,  4:Yellow,
              5:Cyan,  6:Magenta,  7:Orange, 8:Pink
       (If White is selected (ALT/W or ACGW) then pen 1 is used.)
 Pen velocity:(cm/sec) 1-100 [Fast]: The default <RTN> will set the plotter to
 full pen speed and acceleration. To plot on foil use range 5-15. Maximum
 speed on an HP7475A is 38.1.

GRAPH Plotter driver:

 When the GRAPH plotter driver is loaded, the Print to Printer command
 is not available
 The "*" is replaced by "P", and "Plot" replaces "Print" on the command line.
Plotter command (P):
 Type: P then select: A (Append), C (Create), D (Direct), E (End), J (Join),
       L (List), R (Run) or S (Setup).

 Note: The Plotter Setup [PS] menu will be automatically entered if any of
       the plotter commands are used first.

Setup [PS]:
 Select Graph plotter, Printer or External, then for plotter or external,
 also select paper size [A4], scale (1 to 100)[70],
 Rotation [0] or 90 degrees, Heading and Free-text size (1 to 9)[2],
 number of pens (1-8[6]) and pen velocity (1-100 or [Fast]).
 Setup may be used at any time to change parameters.

Colour selection:
 In the Graph program use ACxc to select colour prior to selecting the
 first graph command and AFTER selecting Plot Create, Append or Direct.
 Text:ACTc   Graph:ACGc   Frame:ACFc
 e.g. ACTR (Selects Red text for all subsequent text.)
 For multiple graphs and Pie/Bar charts, the colours will automatically
 increment until the last pen, then cycle from the first pen (pen 1).
 In the Draw program, use ALT/T to select text colour.

Free text (headings etc):
 In the free-Text mode in the DRAW program, (T command) the plotter can be
 treated like a typewriter.
 Cursor keys and backspace are active.
 The Draw Text command [DT] in the GRAPH program also allows text files to be
 plotted.

Append [PA]:
 Append all subsequent graph-producing commands to those already
 in an existing plotter disk file.
 The first character of menu line changes from P to: A

Create [PC]:
 Start a new plotter file. Once this command has been
 selected, the first character of the menu line changes to: C

 All subsequent graph commands will produce plotter driver commands
 and output them to the disk file.  These commands are then immediately
 (or later) output to the plotter (or printer) with the PR command.
 To exit Create mode, type: PE  (Plot End). The plotter commands are saved
 in the disk file (name.GTG).
 (Note: If Setup (PS) has not previously been selected, the Setup menu
        will appear first. Then follow Setup with the PC command.)

Direct [PD]:
 All subsequent graph commands will output directly to the plotter
 as well as the screen. (Not applicable if outputting to a printer.)
 Terminate with the PE command.
 The first character of the menu line changes to: D

End [PE]:
 Turns off plotter output either to disk or direct. All subsequent
 Graph commands will only appear on the screen. Any file being
 created or appended will be closed.

Join [PJ]:
 Join plotter files on disk together. ( A library of plotter
 files can be created and joined to form new files.)

List [PL]:
 List on screen the contents of a plotter command file (HPGL).
 To pause the list, press SPACEBAR. SPACEBAR to continue.
 To terminate the list before the end, press Esc then <RTN>.

Run [PR]:
 Outputs plotter commands from a disk file to the plotter. You
 may choose to use the saved parameters ([F]ile) or those input with
 the last Setup command (Current).  (i.e. Paper size, scale and
 rotation can be altered just prior to runtime.)
 Notes: 1. An existing screen image cannot be output to the plotter.
 It must first be generated with the Plot Create/Append command.
        2. If Printer had been selected in the setup, the PR command will
 automatically  output to an Epson/compatible printer.

 To return to the GRAPH program, enter the DG (Draw Graph) command. Use the
 DD command to transfer directly to DRAW plotter driver.


 Pie chart notes: For best results, use thicker pen (0.7mm) for pen 1.
 CGA Screen: Must be set up in low resolution (320x200) to allow
 colour selection. EGA screen must be in high resolution (640x350). Once the
 Pie plotter file has been created, use Plot Append to add further text,
 border etc.
 Dot and Bubble Charts: When creating a plotter file (or Direct), the dots can
 be Open [O], filled with a cross-hatch pattern [P] or solid fill [S].

DRAW Plotter driver:
 When the DRAW plotter driver is loaded ([GP] from the DRAW program), the menu
 header [DRAW] is replaced with "P DRAW".

 A number of the Draw commands are not available for the plotter: These are
 the Block ,Paint and Rubout commands. (Fonts 1-7 are also not available.)
 All plotter control commands are Px where x is A (Append), [C](Create),
 D (Direct), E (End), J (Join), L (List), R (Run), and S (Setup).
 These are identical to the GRAPH equivalents.

Note: Files and commands created by the Graph program can be joined/appended
      to files created by the Draw program and vice versa.
