Reverse/flip values in the colorbar axis

113 views (last 30 days)
Hi,
In the attached figure, I have reverse the values in the color bar i.e. red to be positive and blue to be negative. Please help me with this. I have tried flipud, but it changes the color pattern in the contour.

If you want exactly that colormap, but flip it you can do this:
cmp = colormap;
cmp = flipud(cmp);
colormap(cmp);
You should be able to re-set the colormap to jet in one call:
colormap(jet)

Not that I disagree with your request for additional colormap-utilities, but "teribly cumbersome" might be a bit of an exageration for what can be done with something as simple as a one-liner:
colormap(flipud(colormap))
that is only 26 characters...

I tried some above codes... but I found working for me is:
colormap(flipud(jet))
