if you were able to do grouping and then a summary on the group you could do a group select to exclue the groups that = 0. I think the graph is created after the group select so they would be dropped out. YOu may want to do a quick test of that first though.
Otherwise you may have to do a subreport that mimics this concept or stored proc that sets NULLs into the data set so they would be dropped from the graph via use of that field.
