void polar (mode) POLPLT.C Level 3
 
char mode = 1 to make polar contour plots.
= 0 (default) to turn off polar contour plots.
 
polar() allows you to make polar contour plots. It must be called before you call any of the contour plot routines. Polar contour plots cannot have numeric labels inserted into the contours, so you may want to use a legend to identify contour heights.
