** Sheet View's Plot Menu Commands


Û  Plot menu

    This menu contains commands that
creates new graphs.  There are several
2D and 3D plot types.  Although it is
easy to create and modify plots with
TechPlot, thought and planning are
still required in order to produce a
high quality graph.  The first step
is to decide on the most suitable plot
type.  Many different plot types can be
used to display the same data set, but
some are more effective than others
under certain circumstances.


Û  2D Curve

    This menu contains three 2D curve
related commands: scatter/line, polar,
and error bar.  These plot types (2D
rectangular curve, polar curve, error
bar) are the most common methods of
graphical representation.  These commands
produce 2D data plots with or without
line connection.  If the data set
represents observed data points, then the
plot will be just the data points listed
on the data sheet.  If there is a model or
function in connection to the data you
selected, a smooth curve will be produced.

Û  XY Lines

    This command sets up 2D line and
  scatter plot types in a Cartesian
  coordinate system.

Û  Polar

    This command sets up 2D line and
  scatter plot type in a Polar
  coordinate system.

Û  Error Bar

    This command sets up 2D error bar
  plot type in a Cartesian coordinate
  system.


Û  2D Bar chart

    This menu contains commands to create
a 2D bar chart.  A bar chart plot draws
perpendicular bars from either the x-axis
(vertical bar) or the y-axis (horizontal
bar) to the data point.  Group bar charts
are created by adding more than one column
to the plot.

Û  Vertical bars

    This command displays the Bar Chart
  dialog box which lets you set up 2D
  vertical bar plot type in a Cartesian
  coordinate system.

Û  Horizontal bars

    This command sets up 2D horizontal
  bar plot type in a Cartesian coordinate
  system. 


Û  2D Special
    See TpSht_04.hlp (Index 43).



Û  3D Curve

    This menu contains commands that
creates a 3D curve graph.  There are
three coordinate system available in
TechPlot:  Cartesian (x, y, z),
Spherical (r, é, è) and Cylindrical
(r, é, z).

Û  Scatter/XYZ-Line

    This command creates a 3D XYZ
  scatter/curve graph.

Û  Sphere

    This command creates a 3D Spherical
  scatter/curve graph.

    Note, in the spherical coordinate
  system, X is the é angle, Y is the è
  angle, and Z is the radius (r).  The
  graph is drawn in the XYZ Cartesian
  coordinate system.  The relationship
  between the Cartesian system and the
  Spherical system is:
        X = r cosé sinè,
        Y = r cosé cosè,
        Z = r siné.

Û  Cylinder

    This command creates a 3D Cylindrical
  scatter/curve graph.

    Note, in the spherical coordinate
  system, X is the radius (r), Y is the
  angle (é), and Z is the z-axis.  The
  graph is drawn in the XYZ Cartesian
  coordinate system.  The relationship
  between the Cartesian system and the
  Cylindrical system is:
        X = r cosé,
        Y = r siné,
        Z = z.

Û  Error Bar

    This command creates an Error Bar
  curve graph in Cartesian coordinate
  system.


Û  3D Bar chart

    This command creates a 3D bar graph.

Û  3D Surface

    This menu contains four commands that
create 3D surfaces.

Û   XYZ

    This command creates a 3D Cartesian
  surface graph.

Û  Sphere

    This command creates a 3D Spherical
  surface graph.

Û  Cylinder

    This command creates a 3D Cylindrical
  surface graph.

Û  Block

    This command creates a 3D Cartesian
  surface graph.
