Greetings guys,

I want to change the elevation numbering on a polar plot. In a normal plot, the counting will go in an ascending order from the center of the plot (20,40,60,80) but is it possible to change it in a descending order from the center (80,60,40,20)? I have attached 1 polar plot edited in paint showing what I need.

Thank you very much!

An outline of how polar() works is at http://www.mathworks.com/matlabcentral/answers/36391-how-to-plot-multiple-polar-graph#answer_45557, though it might have changed as R2014b.

You might want to use http://www.mathworks.com/matlabcentral/fileexchange/38855-comprehensive-polar-plots/content/mmpolar.m as it looks like you could configure RTickLabel and RTickValue. That is, you would tell it at R value 20 to put the label '80' . Remember that the rho you should pass to the function should be 120 minus the rho of the data in order to get it to draw inside out.
