out how to turn off the Cartesian grid, but need to display angles from 0-360 or -180 to +180 around the circle instead of x-y coordinates.

<p class="xmsonormal">Has anyone done polar-format gnuplots in LON-CAPA? Would you be willing to share an example? This is my first foray into polar gnuplots. I am having trouble getting the angle to display around the perimeter. It’s rendering x- and y-axis
values instead of angle and radius values.<o:p></o:p></p>
