I have multiple canvas and sometimes one or more might have nothing to
draw (no data).
Currently I just call.
canvas.draw()
canvas.Refresh()
for each of the canvas, but this gives me an error if there is no data.
Is there a built-in flag I can check before calling draw? Or do I have
to keep

Yes, it needs to be updated -- best would just be to remove the
contents there and point to the mplot3d on the mpl website. Can you
do this for

We want a complete, free standing example that exposes the bug, with
any additional info like mpl backend and version number.

Yes, indeed. It looks like nice stuff!
I do encourage you to keep up the good work on this (the only thing I
notice is the need for some more docs). I also encourage you to keep the
contour generating code separate from anything matplotlib specific. I,

I don't think your approach will work in general.
When you move an axes from one figure to the other, you have to update
the transform attributes of all the artists, which, I think, could be
tricky to do for general cases.

Hi,
Is there a standard way to compute first and then plot something
later? For example, I would like to generate a fine contour plot,
then use it as a background later.
x = np.linspace(-1,1,1000)
X,Y = np.meshgrid(x,x)
Z = ((X*X + Y*Y) - 0.5)**2 + Y**2
contours = plt.contour(X,Y,Z,100) # T
Hi all,
I am a beginner with matplotlib and doing my first steps with python
plotting.
However, I learned that pyplot.show really forces the display of already
existing plots.
For instance, when I type
In[2]: pyplot.plot([1,2,3])
Out[2]: []
nothing happens until I type
In[3]: pyplot.show()
may be you can try pyplot.ion()? it turns interactive mode on.
Hope this helps.

Hi,
thank you for the quick reply. Unfortunately, none of both works for me.
values = [1,2,3];
pyplot.ioff();
#pyplot.ion();
print pyplot.isinteractive();
pyplot.plot(values);
pyplot.show();
The value (True|False) of interactive mode does not make a difference to the
plotting.

oops, maybe use pyplot.ion() not pyplot.ioff(). and pyplot.show() is not
needed.
just pyplot.plot(values) is enough to launch a new figure window and you can
continue plot new lines or legend... interactively.
I test it on my pc: Windows XP, Python 2.5.4, Matplotlib 0.99.0.
