RE: 3D plot. Please help!Origin does support the plotting of multiple datasets in 3D. However, I am confused as to what exactly you want to do and what exact plot type you are using.
If you could please email me a more detailed description of your problem to tech@microcal.com, I would be glad to help you. If you could attach the Origin OPJ file which you are working with, this would be most helpful.
