Hi,
is there a way to update a contour plot? I need to display a series of
contour plots from a directory with data files and want to view them
consecutively, preferrably without building a gui for it. Is there an
easy way out?

Hi,
I'm having trouble building matplotlib 0.99.1.1 (transcript below).
I'm using copies of Python (2.5.1) and Tcl/Tk (8.5.5) that I have
built myself, and that are apparently working fine. Previously, I was
using this exact procedure to build 0.91.4 without any problems.
Any suggestions would

transforms for different vertices?

data coords, but whose width is a constant in axes coords regardless

Hi all,

Hi Ralph,
I don't think there exists a function like the line-'set_data'-method for
collections, which are generated by 'contour'. This particular method of

Well, I've been starting working on a pyglet backend but it is
currently painfully slow mainly because I do not know enough of the
matplotlib internal machinery to really benefit from it. In the case
of glumpy, the use of texture object for representing 2d arrays is a
real speed boost si

Hello,
I want to dynamically update a plot of the rate at which a neural network is
learning a function. Ideally, my python program would open up a window and
update the plot inside of it after every training epoch.
I have written the following code to do so:

The second case does not do what I want, which is to pad the text on

I'm trying to 'automate' a few components within basemap. I have a pretty
complicated, and assuredly poorly written, set of functions that allow me to
'dynamically' plot a grid of data (lon,lat).
Here is one section where I try to deal with transforming the data based on
the projection. 'data' is
I don't think the transformations framework is going to be of much help
for automating this. You seem to be suggesting an x-axis where the
center is in data coords and the width is in axes coords. Once you've
added the two together, it will be impossible to separate them.
I think the path of

If I understand correctly, the top and bottom of the box are in data
coordinates, the x-center of the box is in data coordinates, only the
width of the box is in axes coordinates. Is that correct? If so, a

Is the attached sort of what you want? It defines a custom rectangle by
(x, w, y1, y2) and overrides the get_transform of the patch to update
itself at draw time.

Well, you could just script it and create .png files I do it all the
time.

I can confirm this with latest svn. I take a quick look at the code,
but couldn't figure where the stripping happens and I hope other
experts to step in.
While I think you're not using usetex mode, you may use tex's own
spacing command with usetex mode. Depending on your need, you may also

Jeff,
Right now, for me, any Basemap example that uses colorbar() is broken
for me. I think there's a problem with how Basemap sets the current
'image' so that a colorbar can be automatically generated for plots.
The code currently does:
plt.gci._current = ret
I think the current image hand

Greetings,
I would like to plot to make a figure with 3 subplots
of the form (221) to (223):
- each subplot should show a bar3d plot of a matrix
- each subplot should have it's own title
The problems:
a) I don't see (nor did i find something) how i can
use subplots combined with bar3d (f
You need an empty mbox at the end of line (\mbox{}).
text(xlim()[1],1.02,r'$r^2$~~~\mbox{}',horizontalalignment='right')
If you did mean \; after ^, it requires {}.
Again, these only works if you use real TeX for text rendering (ie
usetex=True), not the mpl's mathtext mode.

Hmm, I'm afraid that this only works if you use preview mode. I
haven't tested, but I guess it will fail without it. Check if

Hi Mike,
This is definitely on the right track. Thanks a lot for writing it
out. When I change the view limits, indeed the width stays constant
while the height gets rescaled. However, when I try to change to a
logarithmic axis, I get the following errors. Again, excuse my
ignorance, but I am

The exception will go away if you explicitly use np.array as below.
box = np.array([[self.x, self.y1],
[self.x, self.y2]])
However, note that Mike's example has x-center at 0.

Try below instead of Axes3D. Obviously, "131" is the geometry
parameter for subplot command. You don't need to add "ax" to "fig"
since Axes3D do that by itself.
from matplotlib.axes import subplot_class_factory
Subplot3D = subplot_class_factory(Axes3D)
ax = Subplot3D(fig, 131)
This will show yo

After experimenting with colormaps for a while, I was able to make both
discrete (piecewise-constant) and continuous (piecewise-linear) colormaps
work. Although colormaps can be created directly using
LinearSegmentedColormap from the matplotlib.colors package, this is a
tedious and error-prone pro
