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".
