I've got a a pylab 2D array which I plot using imshow() which just works
fine. But part of the data within the array is not to be considered nor
plotted. To keep it simple let's assume the data I need is shaped like a
triangle. It is no problem to extract the data from the matrix
converting the matrix to a list and dropping all unnecessary data.
My problem is that I don't know how to plot the data again. A possible
work around would be to set data elements which I don't need to some
value not in the data. But I since I need to compute histograms for the
data, for example, I have to drop the data anyways. Is there a way to
solve my problem?
Thanks for your help.
