Legend for Pcolor

Nathan — Tue, 21 Oct 2008 02:06:02 -0400

I have been using pcolor to plot my data which has already been compressed to discrete values normally ranging from 0-6. The commands are just

pcolor(mymatrix) %with discrete values ranging from 0 to 6
colormap(grey(7))

I would like to have a legend with entries for each discrete value and have had no luck with the following:

legend('LabelFor0','LabelFor1','LabelFor2','LabelFor3'....

Does anyone know how to get a legend like that to work with pcolor?

Thanks

What you're describing sounds more like a COLORBAR than a legend.
