Re: [sympy] Re: sympy gamma

Gamma uses its own plotting code based on d3.js, which is all rendered client-side and does not support all types of plots (particularly 3D plots). Matplotlib would allow us to support that in Gamma. We wouldn't necessarily be writing code using matplotlib, but instead trying to get matplotlib

Right, console access is not available for the user to interact with the plot. In the sympy documentation it's been mentioned that the plotting module supports both 2D and 3D plots. http://docs.sympy.org/latest/modules/plotting.html Also what type of console would you like to have and how to

Re: [sympy] Re: sympy gamma
