So you suggest that I transform each value of the array to it's log value
Yes, using the transformation I indicated.
and then apply the [pl]shades?
Yes.
Would it be quite resource consuming?
The plshades call would be no slower or faster because it is plotting an array of cmap1 indices in the range from 0. to 1. just as per normal. There would be some extra time required before you make that call to convert your array into that 0. to 1. range via the log transformation I suggested, but that time should be negligible with today's computer speeds. For example, you should be able to do the order of 100 million of such transformations per second assuming a 2GHz machine, and assuming a mathematical transformation would cost ~20 machine cycles per array value. Anyhow, good luck with this and let us know how it goes. Alan __________________________ Alan W.
