[Matplotlib-users] sharing labels and legends across subplots

2009-10-11 Thread per freem
hi all, i am trying to share both an axis label (but not the entire axis) and a figure legend across a set of subplots. that is, i'd like to have a figure where there is a major enlarged ylabel that is meant to label the entire row of subplots and a main figure legend, rather than individual legen

Hi Michael, I suppose I'm a bit confused -- I thought that jpeglib, part of which is implemented by PIL (??) could process compressed images without representing decompressing them to a dense raster-image matrix (http://en.wikipedia.org/wiki/Jpeglib). That said, I tried to do some PIL things, an

[Matplotlib-users] plot color as a function of values?

2009-10-11 Thread Xavier Gnata
Hi, Imagine you have something like: from pylab import * t = arange(0.0, 2.0, 0.01) s = sin(2*pi*t) ax = subplot(111) ax.plot(t, s) That's fine but now I would like to plot the negative parts of the curve in red and the positive one in green. Is there a nice pylab oriented way to do that? Some

hi all, i am trying to make horizontal (as opposed to the default vertical) rotated labels for axes in my subplots. i tried using the 'orientation' optional argument, as follows: from numpy import * from scipy import * from mpl_toolkits.axes_grid.axislines import SubplotZero import matplotlib.pyp
