Hi,
You could have a look at this 3D demo:
http://matplotlib.svn.sourceforge.net/viewvc/matplotlib/trunk/matplotlib/examples/mplot3d/wire3d_animation_demo.py?revision=8015&view=markup
I think you can do something similar to your matlab file using mplot3d.
Cheers,

All,
I've attached lorenz.m from Matlab. It animates the trajectory of the solution
of the lorenz system in 3D.
Does anyone have a Matplotlib file that will do something similar?
David.

Good afternoon group,
I am developing an application that had always before plotted a variable 2D
numpy array of floats using contourf(), and then saved the figure produced as
.png. Certain runs of the application (the ones with best precision) result in
a failure while saving the figure using
This has indeed been fixed.

This looks like a pretty nice algorithm:

Dear all,
I new to matplotlib and I need some help with a very simple procedure.
I've been successful to plot dates on the x-axis with the "plot"
command. However, I've been unable to use dates with the contour and
contourf commands.
The command I'm using is:
CS = contourf(time, depth, dens)
Hi,
I've got data in terms of day numbers, and wish to plot it as a 2D
scatter plot, with the color denoting the day.
I'd like the colorbar to be annotated in Apr 7 type format...
I've tried the following code without success.
import numpy as np
import matplotlib.pyplot as plt
from matplotlib.d

It was indeed a backend issue, fixed now. Thanks!

I'm not sure what the cause may be, particularly since I can't reproduce
it myself with matplotlib 0.99.1.1.
What backend are you using? Agg, Cairo and Wx all check out for me.
The examples you point to don't look like Agg output to me... Do you
have anything in your matplotlibrc?

Hello,
I think I'm using matplotlib 0.99.0. IndexFormatter in matplotlib/ticker.py
doesn't appear to subclass Formatter which I think might be a bug. I did a
quick search of the changelog for 0.99.1 and I couldn't find any mention of
this issue.

I use matplotlib since two days only. I have done some things pretty
good but I am now in front of a problem an I didn't found a solution
in the documentation.
I would like to draw the surface defined by the lists X, Y and the matrix Z.
I get to a nice graphical output with the following code.

For eps files, I use epstool:
epstool --copy -b file.eps file_cropped.eps
It does not leave any whitespace, which is sometimes annoying.

Hi Ronald,
I use:
fig.savefig('graph.eps', bbox_inches='tight', pad_inches=0.03)
Play with the parameters and see what you like.
Hope that helps.

Dear matplotlib users,
I've been successful to plot 2-D lines with dates in the x-axis directly
like:

Where times starts at 1998-01-11 01:00:00 and ends at 1998-02-06 08:00:00
(633 elements). and dens has 10 elements. Now I'm trying to make a contour

Does this example work for you?

I don't have scikits.timeseries installed, so I can't confirm whether
your original attached example works or not. Can you produce a
standalone example that reproduces the problem?

Hi Nico,
I'm not sure, but one reason could be different backends. What kind of backend
are you using on the 2 machines?
import matplotlib.pyplot as plt
print plt.get_backend()
( and what version of matplotlib
import matplotlib
print matplotlib.__version__
)
In case the backends are d
OK, I've done more tests.
The problem occurs always when plotting data from masked array with lines.
When there is a masked field in the array, drawing is stopped, and so
if the first element is masked, no output can be seen.
When all fields are unmasked, there is no problem.
Also, drawing with
Hi,
somehow I don't manage to set up matplotlib such that I can draw
animations. I've been using the moving sin example from
http://www.scipy.org/Cookbook/Matplotlib/Animations
which spits out nicely moving sin-waves on one machine, but does
nothing on the other. I'm puzzled. Checked pylab.is
hello,
I'm a quite new user of matplotlib - currently I'm working with

I can draw scatter plots with dots ('.'), but when using lines ('-',

Hello List,
Does matplotlib have a routine that can fit a cubic Bezier curve through an
array of 2D points?
I saw some Bezier routines in Path, but couldn't find what I am looking for.
If matplotlib doesn't have it, does anybody have another suggestion in
Python?
Thanks,

Hi Pierre,
I'm not sure I understand correctly - maybe you could provide a small
stand-alone example which illustrates your problem.
For me the following works fine:
ax = axes()
ax.bar(arange(10), np.random.uniform(size=10))
xticks(0.5+arange(10), ["$a_%i$" % (i) for i in arange(10)])
xlim(xmax
Dear all,
I am facing a small problem with xlim and xticks and nor google nor the
api helped me (one of the reason being that I likely don't know the
exact term I am looking for).
I am plotting a barplot using pyplot and bar() on matplotlib 0.98.5.2.
If I do not use xticks the x axis goes from 0
