Polar plot
| Syntax: |
GRAPH\POLAR r theta
|
| Qualifiers: | \AXESONLY, \OVERLAY
|
| Defaults: | axes drawn |
| Examples: |
GRAPH\POLAR R THETA
|
If either the \POLAR qualifier or the \RADAR qualifier is used, the input variables,
r and theta, are assumed to represent polar coordinates, where r
contains the radial components and theta contains the angular components, in degrees.
A polar plot is always autoscaled. The radial axis at 0° always has a minimum value of zero.
The maximum value of the radial axis is determined by the data. All 360° are always displayed.
By default, four radial axes are drawn, but any number of axes can be drawn using
the POLARNAXES characteristic. Only the
radial axis at 0° can have numeric labels and the optional text label. Circular grid
lines can be drawn, and are controlled by the
POLARGRID characteristic.
The location of the origin of the polar plot is controlled by the
POLARORIGINX and
POLARORIGINY characteristics, and the
length of the radial axis is controlled by the
POLARAXISLENGTH characteristic.
Use the \POLAR qualifier if you would like 0° to be horizontal through
the origin. Use the \RADAR qualifier if you would like 0° to be vertical.

The user has control over the polar plot by means of the Polar Characteristics.
