Thanks a lot for the contourf function! Just fyi, the [~, ixMA] at line 137 gives errors on old (i.e. 2009) versions. Another question... are you implementing a way to specify the contour values rather than the number of contours?
Wow, that is cool, thanks!
Question: I am using a contourf plot and adding the map behind. So I set the colormap and the transparency for the contourf, but all colors change when I plot the background map. Any idea where that could come from?
