Hi David,
The XROI procedure is the first thing I tried, but I don't understand
how to get the actual values I've already calculated in the histogram.
This is why I started doing it in a different way. If I just send the
image, I get the occurrences over 0-255 and if I send the actual data,
which is an array, I just get a little image that I can't really even
see. If I send the array of masses, the latitude array, and longitude
array, I just get three tiny images. Do you know how I send XROI the
real values of the pixels (n-g/m3, not 0-255) and still have it
displayed as a map? I guess that's what I really need and just can't
figure out how to do that.
Emily
