Hi Mary:
Thank you for the code snippet. Snippets are much better than my gob.
Anyway, I don't think I have explained the point of the code yet.
We have a intervals, 0,3,6,9,12.
We have data for those intervals (4,8,3,1). This could be 4 model grids
with between 0-3 inches of snow, and 8 grids with between 3 and 6 inches of
snow, etc.
Then, our total would be 16 and we make the histogram that corresponds with
1,2,3,4 values of
the array we're plotting as 1111,22222222,333,4. This is the data that
gives the correct values when
using your histogram function.
I don't think there is a simple way to use the histogram function on
processed model data without going through this transformation.
