Hi,
I was having the same problem until I figured it out:

Type

caxis( [a b] )

after your pcolor instruction.
This will change the "color axis" of your figure so that its minimum will have value "a" and its maximum will have value "b".

For example, if in your color scale red corresponds to the highest value and blue corresponds to the lowest value,

caxis( [0 5] ) will set the color axis so that blue means 0 and red means.

Hope this helps.
