Hi,
I am using scatter to generate a 2-D plot. My y-axis values range between, let's say, ylim([-100 100]). The direction of the colorbar, in the jet color scale, will be "dark blue" for -100 up to "dark red" for 100. Is there any way I can have a double direction colorbar centered around zero? For instance, 0 will be the "dark blue", while -100 and 100 will be the "dark red". Of course the colors inbetween will correspond to the values between [0 100] and [-100 0].
