I'm new to matplotlib (and am loving it!), but am getting frustrated. I have a polar grid represented as a a 2D array. (rows are radial sections, columns are azimuthal sections)
I've been able to display the 2D array as both a rectangular image (R vs. theta) using pyplot.imshow() and as a polar plot using pyplot.pcolor(). However, pcolor() is painfully slow for the size of the arrays I'm using, so I want to be able to display the array as a polar grid using imshow().
Using pcolor(), this is as simple as setting polar=True for the subplot. Is there any way to display the 2D array as a polar plot using imshow()? without having to do coordinate transformations on the entire array? Thanks in advance
