I tried to follow the instructions given on
http://blog.hyperjeff.net/?p=160
and modified the make.osx accordingly to compile matplotlib on OS X 10.6.2
(Snow Leopard).
But after executing
sudo make -f make.osx fetch deps mpl_build mpl_install
I get the following error message:

Just two thoughts:
1) I doubt the statement cited above is not correct, as it may also
yield negative values as soon as 0 < x < 1. In fact, you are
calculating log_{largest}(x). This crosses zero for x = 1. Wh

Thanks, adding the axes ([0,0,1,1]) helped!
:)
I'll just be careful so that my calculation domain
is from 0 - 1 in x and y direction, this is something
I have to do anyway. This will definitely work!
Thanks again,

Hello,
I am trying to plot multiple intersecting lines from a given
array. In order to visualize the amount of crossing points I am
setting a certain alpha. However the crossings do not get darker as I
expected.
That is what I tried::
import numpy as np
import matplotlib.pyplot as plt
Oh, nice.
I've been flagging particularly useful-looking answers on the
matplotlib mailing list for a while; I have four or five hundred
marked. I don't want to do all the cleanup to make them an inoculant
for a new site, but perhaps they would be useful for people to do a
few each or thr

Hi,
I am trying to create an image from an array using PIL, numpy and a
colourmap from matplotlib.
I got the colourmap by using ipython and the following code
colourmap = []
for i in xrange(256):
r,g,b,a = cm.jet(i)
r = int(round((r * 255),0))
g = int(round((g * 255),0))
b = int(
Hi,
you can create your supporting points on a regular r, phi grid and
transform them then to cartesian coordinates:
from mpl_toolkits.mplot3d import Axes3D
import matplotlib
import numpy as np
from matplotlib import cm
from matplotlib import pyplot as plt
step = 0.04
maxval = 1.0
fig = plt.figur
The code below works perfectly. I think this should be included as an
mplot3d codex. I'll look into what's required to submit a new example
to the documentation.
Thanks Armin!

I don't see a reason why this can't be implemented. It is probably pretty
simple to change the surface plot code to use a polar grid instead of a
rectangular grid. Of course this won't change the look of the rectangular
axes, but maybe that is not a problem.
I invite you to take a shot at imp
Hello,
the following will display a figure with a plot. the figure will embed
the classic toolbar.
import matplotlib.pyplot as plt
import numpy as np
x=np.arange(0, 1, 0.1)
fig = plt.figure()
ax = fig.add_subplot(111)
ax.plot(x)
plt.show()
from there, is it possible to add new buttons to the too
Looking at set_ticks_position doc it says that "default" will reset
ticks to be on both sides and labels on left, and set_label_position
only allows for left or right.
Is there any way to have ticks and ticks labels on both left and right?
