Have you ever wanted to do a contour plot of data in polar coordinates but didn't want to go through the hassle of converting it all to Cartesian coordinates? Well if so, here's your answer. A simple scriptlet that works exactly like MATLAB's built in contour plotting function. You can use clabel and handles just like contour. And if you don't like it, I'll give 100% of your money back (less S&H)
