Reverse the colorbar axis

I have a contourf plot, which I plotted across the range 2 to -2. I have edited the colormap to get it to move between green and brown.

I don't want to change the colormap, or the values that are associated with each color. All I want to do is essentially flip the colorbar, so that -2 is at the top, and 2 is at the bottom.

All the solutions I have found so far only flip the colors, which is not what I want to do.

I'm basically looking for an equivalent function to: set(gcf,'YDir','reverse') but for the colorbar.

I'd appreciate any help I can get. Cheers, Claire.

How did you flip just the colors and not the axis?

The call to colorbar returns a handle. There's lots of options in there to set, and you'll find the one you wanted, too.

h = colorbar;
set( h, 'YDir', 'reverse' );

That's exactly what I was after! I didn't know that you could use 'YDir' for the colorbar.

Thanks so much!

Another solution is

cm = colormap;
colormap(flipud(cm));
