In a pcolor plot, how do I make values with 0 blank or set the color scheme to a set range?

Basically, I need to be able to set the the color scheme to a range so I can see certain values.
I have measurements that are about .1700, but they vary by about .001 and I want to see that variation. The problem is that I have 0 values (for formatting reasons) and they make it so I can't see the variation.
I would like to be able to set a range for the colors.
Red = max value
blue = min value -= 0

The easiest way to go is to turn all zeros into NaN's (not a number) like
Data(Data==0)=NaN;
Then they dont appear in the plot. otherwise you have to use the colormap editor (rightklick on the colormap -> colormapeditor). There you can shift the arrows and change the colors. Afterwards you can save the colormap by
Colmap = colormap;
and use the scheme again in another plot like
colormap(Colmap);
