POLARGRID

Syntax: SET POLARGRID n
GET POLARGRID { n }
Default value: POLARGRID = 0

POLARGRID controls the number of grid lines on a polar plot.

If POLARGRID > 0, draw a grid line at every POLARGRID large tic mark, starting with the first.

If POLARGRID = 0, suppress all grid lines.

If POLARGRID = -1, draw a grid line at every polar axis tic mark, large and small.

The GRIDLINETYPE characteristic controls the line type of the grid lines.

For example, the following picture shows an example polar plot with POLARGRID = 1
