Hi Bruce,

Thanks for your quick reply. I tried fine-tuning the offset and the midpoint. I guess what I would like to have happen is to have a couple more colors come out beyond the blue-to-light blue range for the thinning. If I could get some greens in there too, that would make the picture much more descriptive to look at. Thanks for your help!

Regards, Jeff Sadino

Hi Jeff,

have you tried setting the offset in the configure functional overlay panel to be around the middle of your range (-1.5 or so I guess)?

Hello Surfers, I have an overlay file with values ranging from -4.63 (n=138477) to 1.34 (n=25365). I would like to display this data with more than the two colors of the Green/Red, Heat, Blue/Red, or complex Color Scales in the Configure Overlay dialog. So far, no luck, even with toying with the min, max, mid, and piecewise options every way I can think of. Is there some way to get a fuller color spectrum on my overlay?

Thank you, Jeff Sadino
