I'm trying to make some proper energy plots with consistent sign conventions. Basically, I'd like a color bar with -170 at the top, -20 at the bottom, intervals of 10. I've reversed the default palette to get -170 red and -20 purple, which works, but I can't find a way to get the color bar and labels to reverse. I've tried every possible combination of levels, this is the one that I thought would work: fill/level=(-20,-170,-10)/palette=inverse_rnb/nolabel var_obs[i=6:83,j=6:53]/21600, x_page, y_page but unfortunately doesn't. thanks in advance for the help. jonathan
