Re: [Matplotlib-users] Export 3D plot to 3D file format
Is the savefig function what you're looking for ? http://github.enthought.com/mayavi/mayavi/auto/mlab_figure.html Note that as far as I know, the .mtl file associated with a given .obj file is not handled properly - all your colors will be white. Personally, I export in .vrml which suits my needs better, as it does handle colors in a satisfactory way.

Ah mayavi...

[Matplotlib-users] zooming with transforms
What is the most effective approach to perform a 'zoom under mouse cursor'? Currently I use the following code (considering g as mpl.Axes), but set_xlim() is called twice. Is there a better approach? # First zoom result = \ g.bbox.shrunk(DEFAULT_ZOOM_FACTOR,1).transformed(g.transData.inverted()) g.set_xlim(*result.intervalx) # Get the new location of initial event b = g.transData.transform_point([event.xdata, 0]) # Then replace the original location under the mouse cursor result = \ g.bbox.translated(-(event.x-b[0]),0).transformed(g.transData.inverted()) g.set_xlim(*result.intervalx) Arnaud. -- This SF email is sponsosred by: Try Windows Azure free for 90 days Click Here http://p.sf.net/sfu/sfd2d-msazure ___ Matplotlib-users mailing list Matplotlib-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/matplotlib-users

You can check you are editing the correct configuration file with (in the Python shell) : >>> import matplotlib >>> matplotlib.matplotlib_fname() You can also try other backends.
