Hi all,
I'm plotting data which extent, in x, from -1000 to 1000. But I'm only
interested in the values between x = -1 and 0.
I also want to plot on an x log scale. But since the x-values are negative,
I cannot use xscale(log). I can use xscale(symlog) though and this is
the behaviour I want.

Hi all,
I'm using a matplotlib.widgets.Slider on my animated figure. Sometime, I
want to refresh the maximum value of the slider (since new values to plot
were generated).
Is it possible to update the valmax value of the slider? If not, is it
possible to delete the slider and create a new one?

I have a derived class that I copy-pasted from the web somewhere to hide

I'm using matplotlib.image.NonUniformImage() to plot a 2D rectilinear grid

Hi all,
I have defined some shortcuts I often use using pylab.ginput(). I normally
do:
fig = pylab.figure()
fig.canvas.mpl_connect('key_press_event', on_key)
with my on_key function being (simplified):
def on_key(event):
if (event.key == 'q'):

Hi all,
I don't really know where to ask, so here it is.
I was able to vectorize the normalization calculation in quantum mechanics:
phi|phi. Basically it's a volume integral of a scalar field. Using:
norm = 0.0
for i in numpy.arange(len(dx)-1):
for j in numpy.arange(len(dy)-1):
Hi,
I cannot kill a plot by ctrl+c in a terminal (sending the SIGINT) when

What could be wrong? I need that.
Thanx!

Could any of the experts have a look at it and tell me if this could be
useful, please?
Thanks in advance for any comments.
Kind regards

I was looking for something similar. It seems Axes3D() takes the angle as
argument:
import matplotlib.pyplot as plt
import mpl_toolkits.mplot3d as m3d
fig = plt.figure()
ax = m3d.Axes3D(fig, elev = 20.0, azim = 45)
in degrees.

I'm not sure its possible right now to do subplots with 3D.
As for the title, I cannot either put titles on any 3D graphs...

Thats good information to have gathered! It sure will be usefull.
Have you look into the new html5's video tag? You can directly embed ogg in
a page, without flash or any other plugin. Firefox 3.5 supports that, I
think Safari would work too.
See this page for information (and look up the source)
I'm sure everybody find this really sad... If he wants control over the
ploting capabilities, then why not have matplotlib and send him the script?I
know when I switched to matplotlib from matlab I wanted to be able to edit
directly the graph with point and click, but sometimes it is more powerful

Its great news that the 3D is receiving more polish :)
After reading on wikipedia, wouldn't it be nicier to have Phong

Maybe it would be too hard, as the Gouraud seems to be implemented directly
in Agg (from what others just said...)
Anyway, just a suggestion
Hi,
I compiled matplotlib svn revision 7246 yesterday to try the 3D stuff.
From mpl's website, an example for 3D bar plotting is shown[1]. I just don't
understand the axes. From the code, shouldn't X values go from 0 to 20,
instead of 0 to 400 000 like shown on the graph? Where does these values
Hi,
I want to compare data and I am doing so with subplots. Ideally, I would
like the subplot command to fill the columns before filling the rows as
it is doing right now.
Now:
subpot(221) = 1st row, 1st column
subpot(222) = 1st row, 2nd column
subpot(223) = 2nd row, 1st column
subpot(224) = 2nd
Anyone? :(

Hi,
I've been using matplotlib for 2D graphing since two years. Data (3D

3D data is created at each time iteration and saved in a file. For the
