HELP!!! Adding JPanel to JPanel (long code sample)

Question

I need some help here. I have been stuck on this for more time than I care to admit. Now this project is due by Monday(tomorrow)! Why does the graph not appear in the tabbed pane "trend report"?? the TrendReport class on line 2131 creates the graph. Line 56 creates an instance. and line 831 adds it to the tabbed pane. everything shows up except the graph.
