pcolor on map axis

I can successfully create a 'checkerboard' plot using pcolor on a regular axes. What I would like to be able to do is create it on a map axes, so that I can superimpose country borders. Just to be clear, I know how to create a contoured plot (contourfm) on a map axis with the country borders. But I don't want contours in this instance, I want to plot the actual gridboxes (i.e. pcolor on a regular axes). Any advice would be much appreciated.

something similar to pcolorm? I suppose geoshow with displaytype surface or texturemap would work as well.

Thanks. I actually did look for pcolorm but missed it somehow.
