Unless I misunderstand, Nicolas and you want different things. You
want a reversed color map (eg for the case of jet, red would map to
small numbers and blue to large numbers). Nicolas wants a standard
colormap but with the colorbar display inverted (red would still map
to large numbers but for vertical colorbars would be on the bottom and
for horizontal colorbars would be on the left -- the colorbar tick
labels would change too).
Or am I misunderstanding?
