[Matplotlib-users] colormap creation

Can someone please recommend a (semi) automatic way to create the rgb dictionaries needed for colormap creation? Basically, I have a 'general' idea of how I want my colors ordered, but Im finding it difficult to create the smooth transitions by manually editing the rgb dictionary for my custom colo

[Matplotlib-users] mpl.colors.BoundaryNorm question

Hi, I'd like to generate a colormap index based on an array of levels & using an existing colormap (Spectral). However, Id like the cmap index to start at the 0.3 value of the Spectral scale (orange/yellow area) instead of starting at the '0' scale value (red area), and then continue until the 0.8

Nevermind, I found the answer; quiver also accepts the cmap & norm args... Sorry for the double post as well...email/outlook issues... Thanks, P.Romero -Original Message- From: P.R. [mailto:romero...@hotmail.com] Sent: 2009-08-13 9:17 PM To: matplotlib-users@lists.sourceforge

[Matplotlib-users] controlling quiver colors with C arg

Question: If I have an array C with values for the arrow vectors' magnitudes, how can I control the magnitude levels & colors that are assigned to the quiver arrows? I successfully managed to plot multi-colored arrows using the 'C' arg, but I'd also like to control the levels & colors, and also pl

Re: [Matplotlib-users] contourf interpolation/smoothness

Jeff, The docstring is clear. My question was on how to actually create the lats&lons arrays (sorry, Im not a very strong python programmer). Could you please recommend a method for dividing a lat/lon array in half? Again, I apologize for asking such a basic question... Thanks,

Re: [Matplotlib-users] contourf interpolation/smoothness

n handle arbitrary grid sizes & resolutions, so I can't just hard-code the X&Y sizes for the finer grid. Any ideas? Thanks, P.Romero -Original Message- From: Jeff Whitaker [mailto:jsw...@fastmail.fm] Sent: 2009-08-13 7:15 AM To: Eric Firing Cc: P.R.; matplotlib-users@lists.sourceforge.ne

[Matplotlib-users] contourf interpolation/smoothness

This has probably been asked before, so I apologize... Is it possible to improve the smoothness/interpolation used in contourf? I know that the interpolation can be set for imshow(pcolor?), but I couldn't see how to set it for contourf. Right now, contourf is producing some relatively jagged outp
