Well, looks like nobody has an answer to this question. How'bout py2exe or other ways of creating exe files out of matplotlib projects? Has anybody been able to do that? --- [EMAIL PROTECTED] wrote: Has anybody been able to create an exe of their python applications involving matplotlib

[Matplotlib-users] Random colourmap?

Hi, Is there a simple way to come up with a random colourmap? I need to plot discrete values, and I would like that the colours do not show a trend, to easily distinguish them? I read the cookbook entry on Doing your own colormap, but can't seem to bring my mind into it! Cheers! Jose

[Matplotlib-users] day-night terminator and/or solar zenith angle code ?

Hello all, Could someone offer suggestions for (preferably) python code to compute: * day/night terminator position * solar zenith angle I'm developing a basemap application that is required to hide contour data in the night regions of the earth. The projections will be Mercator and

Re: [Matplotlib-users] basemap and omerc

By losing the memory I mean that the grid is no longer rotated; that the rotation I introduced through lat1, lon1, lat2, lon2 is lost. If you look at the latitude of the two bottom corners you see that they are the same, they should be different - for the matlab script they are different. In
