plot an histogram

Hi Bill and All,

I need to plot an histogram... When I make a normal plot I get some spikes I don't like... The idea is to have some sort of boxes representing my data instead of just lines crossing points.

I can do this by adding more points to my flatField but before to proced I would like to know If somebody have thought and solved this problem before, or if visad includes this kind of plot.

Thanks,
