ChartEngine question

Hi,

Is is possible to combine multiple graphs in ChartEngine. I am trying to build a X-Bar/R graph, and I would like to put both the X-Bar, and the range graph on a single graph. However, I would like to put the X-Bar on the top, and the Range graph on the bottom. I can do this using a splitter control. However, as with any QM X-Bar / R graph, it would be better if I can put both on the same graph.

Any thoughts?
