This is not a bug.
The exception is raised simply because "textartist.figure" is None
(and it is None because you never set it).
"textartist" you created is not properly set up (no figure, no axes,
no transform). You may do
textartist = Text(0.5, 0.5, "Foo")
textartist.set_figure(fig)
fig.draw_art
Ted,
How does this example run for you?

I am getting a fault when I try to use Figure.draw_artist() with a
matplotlib.text.Text object. Since matplotlib.text.Text inherits from
matplotlib.artist.Artist, which is what draw_artist() takes, this should
probably work.
Tested with latest SVN code on Linux.

I'd like to set the ticks on the y axis such that they do not display
anything lower than 0, even if part of the graph below 0 is visible.
I tried to do this with
ylocator = AutoLocator()
ylocator.view_limits(0, 100)
self.subplot.yaxis.set_major_locator(ylocator)
but it is not changing anything.
On Mac OS X 10.6.2, with Sage 4.3.1, I have installed matplotlib-0.99.1 with
gui backend (to do this, I set SAGE_MATPLOTLIB_GUI=True before using sage's
spkg installer, which performs some patches on matplotlib that ).
When I use the OS X backend and do:
import matplotlib.pyplot as plt

Hey Ted,
I don't quite understand how you're getting the Z data below. But if you have
3D data in X, Y, and Z 1D-arrays, the griddata function should work for you.

Matplotlib will output Type 42 fonts if the rcParam "ps.fonttype" is set to 42.
Type 3 is the default because it greatly reduces filesize (it embeds only a
subset of the font), particularly with large Unicode fonts like Vera Sans.

Have you tried explicitly calling .clf() on the matplotlib Figure object from
your Tix.Frame.destroy callback?

One more note about Axes3D and mouse rotation. Axes3D disconnects the mouse
callbacks when cla() is called. Which means that if you do this:
self.axes = Axes3D(self.figure)
self.axes.scatter(xs, ys, zs)
self.axes.cla()
self.axes.scatter(xs, ys, zs)
then the plot will have no mouse rotation. T

It is somewhat personal preference:
do you want access to NumPy and pyplot functions
in a single name space or not. But the "preferred"
style is the most explicit:

Hi
I'd like to generate a surface plot using mplot3d. However, Z is not a
function of X and/or Y. It's just a set of scalar values. So, the following
doesn't work:
X = np.arange(2, 102, 2)
Y = np.arange(0, 15.15, 0.15)
X, Y = np.meshgrid(X, Y)
Z = f[2]

Hi Filipe,
you can fist use the quiver() function in the classic way for stick plots,
then use gca().xaxis_date().
Here is a simple example :

t = P.arange(100,110,.1)
u = P.sin(t)
v = P.cos(t)
P.quiver([t],[[0]*len(t)],u,v)
P.gca().xaxis_da

I have an AxesGrid instance of 2x2 subplots. I actually only
want 3 subplots, so I instantiate AxesGrid with the add_all=False
option, and manually add only the first 3 axes to the figure:

from mpl_toolkits import axes_grid
f = plt.figure()
grid = axes_grid.AxesGrid(
Hello,
When I save the figure as EPS, no text shows up.
The problem occurs with the example "embedding_in_wx2.py" and when I use

Is it a problem with MSWord ??
Thanks by advance.
