I can fill between curves using either: xs, ys = poly_between(x, y1, y2) ax = gca() ax.fill(xs,ys, facecolor='b', alpha=0.5) or xs = concatenate((x,x[::-1])) ys = concatenate((y1,y2[::-1])) p = fill(xs,ys,facecolor='b', alpha=0.5) giving http://www.nabble.com/file/p20038095/good.png But, i

[Matplotlib-users] limiting theta in polar axis plots

Is there any way to limit the theta extent in a polar axis plot? There are a variety of angular contexts in which 360 degrees are not necessary. To convey the orientation of an undirected line, you need only 0-180 degrees. The minimum separation between two intersecting lines only ranges

First, are there plans to eventually embed autogenerated plots in the the "examples" section (http://matplotlib.sourceforge.net/examples/ ) in the same way that they're embedded within the user guide? There are plans to do that, and probably to

Hello all, I'm creating a python application what does some calculation and displays the result as two imshow() with respective colorbars as the calculation progresses. Each array is ~8192x50. Updating the image is slow, so I only update every 2 seconds or so, but even doing this a significant

[Matplotlib-users] Can't Import Pylab on XP - runtime error.

Hi, I am a fairly new Python user and am trying to set up matplot lib to work with scipy as an alternative to matlab. I installed matplotlib on my home pc with no problems but I followed the same protocol on my work pc and got the following error when I tried to call in "From pylab import *" :

[Matplotlib-users] Example animation_blit.py Sometimes Works

The title says it all. I need the simplest blit animation I can find and when it works animation_blit.py works quite well, but sometimes it comes up and runs to completion at almost 400 FPS, other times it comes up and nothing is drawn at all except an empty plot. Ubuntu Hardy matplotlib 0.98.

[Matplotlib-users] contour legend

Hello everybody! I'm trying to make a contour plot and add a legend for it. The code is basically --- from numpy import * from matplotlib.pyplot import * # put anything into x,y,z arrays ctr = contour(x,y,z) # plots ok contours of z(x,y) ctr.collections[0].set_label('z') legend() show() --- The l
