plotting and diagramming library

by: Erik Lechak |last post by:

Hello All, I am creating a visual programming environment for python (similar to Matlab's simulink, but for python). For several reasons I have decided not to go with OGL.

by: Andrew Dalke |last post by:

I've been looking for a decent 3D plotting library with support for user selection that works under OpenGl, preferable with wxPython.

plotting with Python

by: dror |last post by:

Hello, I have a problem that actually doesn't even make sense. I have 4 million rows in my database. I want to get all records into a DataReader and then read.

Plotting points to screen

by: Jason |last post by:

If I'm wanting to plot points to the screen (nothing fancy at all for the moment), would you recommend PyGame, PyOpenGL or PIL? Like I said, it's nothing complicated, no flashing wotsits or 3d quad-linear vertexes with bi-linear real-time shading, just simple 'points' a few lines or circles and nothing more.
