I have several contour plots with same x,y, and z ranges. Can I overlay three or more of them to make comparison?

Also, how can I save the overlaid picture? When I save the two overlaid plots into a new file, only one of the overlaid plots is retained if I closed all documents and reopen it.

Sorry, but overlays of overlays won't work, and I'll not likely ever allow that. If I did, you could pretty easily get a recursive situation that would produce an endless loop - say document 1 is overlaid by document 2 and document 2 is overlaid by document 1. That one is obvious, but you could fairly easily construct a similarly bad problem with 3+ documents where the problem wouldn't be so obvious.

What I will do, though, is add overlay information to a saved DPlot file so that if you open a file that uses an overlay, that overlaid document is also opened.

I still hope multiple overlay can be done. It is very useful for me in some cases. I am not convinced that the endless loop is a prohibitive issue. Is it really hard to identify/avoid? Even though, giving users the choice and caution is a better way to address it. I would rather think this is easy to realize.

I'll look into it. No promises on if/when that might be available.
