We should have an example of creating histograms. Christopher, if/when you
get it to work, can you send a small demo to the list or post it at
http://vtk.org/Wiki/index.php?title=VTK/Examples/Histogram&action=edit&redlink=1

You may want to start with something simple like a jpeg with a known/simple
histogram to make sure you're doing it right.
