Hi everyone,
I've made a 3x3 subplot using pcolor. The colorbars of the left and right columns of the plot adopt three values, i.e. 60, 65 and 70. I would like the colorbars of the center column to adopt three values as well, i.e. 62, 67 and 72, instead of six values as it is now.
Can someone help me out?

Hi Greg,
For this plot, caxis is set to caxis([min max]), as I want to show only a range of 12 dB. However, I want to set the range with caxis([min max]) and then force only three values to appear on the colorbar.

Always use a handle,

When you create a colorbar, do it like,
c{1,1} = colorbar;
c{1,1}.Ticks = [60 65 70];
do it for all 9 subplots and you can control your colorbars just by accessing its index.

Try this:
colormap(jet(256)) % Use 256 colors.
caxis([62, 72]);
c = colorbar % Get handle to colorbar
c.Ticks = [62,67,72] % Set tick values.
