In addition to Bill's suggestion, check out the graph.py script in
visad.python which has a histogram function in there that is more
along the lines of what you want, I think. This will create boxes
instead of lines connecting points like hist_test.py does. You can
see an example at:
http://www.ssec.wisc.edu/~tomw/visadtutor/graph.html#histogram
While this is written in Jython, you could adapt it to Java if you
didn't want to use the VisAD Python interface.
