multi-bar with a LineXY

[Dale]

I need a chart that has multiple vertical bars and a line chart in the same chart. Is this possible? If so, what's the best way to do it?

Yes, it is possible. How? It depends. There are more bar-chart features with charts based on the CategoryDataset interface, but if your data is time-based, there is only date axis support for charts based on the XYDataset interface.

You need to look at the OverlaidXYPlot class and the VerticalOverlaidCategoryPlot class...the former is in a better state than the latter, but bar chart support on XYPlots is limited (you would have to extend it).
