I've seen requests in the past for overlaying bar charts with line graphs, and contour plots with 2D plots. If you can point to an example, either on the 'net or in a pic you have (not necessarily limited to these cases), I'd be grateful. There's no doubt that if this subject has occurred to you, I probably haven't envisioned what you have. So let me know at support@dplot.com.

(Before you ask, the chances of displaying this in 3D are somewhat less than none. But thanks for the thought
