Log scale with COLZ option


I am using the COLZ option to draw 3 plots:
one with z value ranging 0.1-2.4
another with z value 10-60
and another with 40-240
and would like to be able to compare all three by eye.

If I set the maximum and minimum values then the first plot comes out all the same colour (for obvious reasons). Is it possible to somehow set a log option with COLZ palette so this is possible?


Can you send a small running macro showing the problem ? my first thought to compare the plot " by eye" would bet to set the same min and max for the 3 histograms.
