Hi all I'm plotting colored contour maps using filled.contour. My levels are very unevenly spaced, with, say, high resolution in the small numbers but ranges that can be an order of magnitude or two larger in absolute value compared to where the action takes place. Aside from transforming the data, is there a way to control the color spacing in the key to the right of the map? Right now I get most of the key length taken up by a couple of colors and the rest all squeezed into thin slices, which also creates a problem with the fourth axis labels getting drawn on top of one another.
Hi Claudia, You can roll your own color key with the color.legend function in plotrix. Just specify the colors you want in "rect.col" and the labels in "legend". Jim
