Actually there are two Pynac's out there, one of them is a sage insider project to replace Maxima as a symbolics backend, since that greatly impacts performance and builds. > > > I am wondering what do you think about simplifying the access and use > > > of the external packages to accomplish some very simple operations.

This is a little frustrating. You pretty much have the same problems as I do, since I'm also an Electronic Engineer. I also find sage hard to use from a non-mathematician's POV (dealing with Fields isn't something one's accustomed to do in Engineering). I have done some plots in sage, but for "real" stuff I have always used pure Numpy+matplotlib, since it gives me more flexibility on setting up plots (like using plot windows). This, however, limits me to numeric calculations. Also, I have tried many ways to do bode plots in sage, but nothing was really good, since sage's plot like to break badly for non-default axes because of automatic point placement. Anyway, I couldn't do more due to time constraints, but some people have recently made some additions to the plot code, so I may take another look at it when I have time. > > Question: is it JMOL suitable for showing 2d plots, and to browse them > (zoom and pan)? AFAIK Jmol is for 3D visualization only. When it works.
