Hello,
I keep getting the error ValueError: Need more than 1 value to unpack
every time I try to use the line ax.plot_wireframe(myArray[:,0],

What does that error mean?
Hi Shir,
I think you used 1d-arrays

One thing I can think of is:

Good day!
Could You please tell me how can I get axises autoscaling in the
animated plot example. I've take an example and have modifyed it
slightly so the second line in plot gets out of bounding box during
animation. What I need is autoscaling of axises during animation. Please
point mee
I'd like to clarify: I want the empirical cdf, but I want it to be
normalized. There's a normed=True option to plt.hist but how can I do
the equivalent for CDFs?

There is no such thing as a normalized empirical CDF. Or rather, there is no
such thing as an
How does Alan's code compare with using cumfreq and then plotting its
result? Is the only difference that cumfreq bins the data?

Also, I am not sure how to use alan's code.
If I try:

plt.plot(ec)
it doesn't actually look like a cdf

Make sure my_data is sorted first.
plt.plot(my_data, ec)

I have some troubles updating a contour plot. I reduced my code to a simple

X,Y=sp.meshgrid(x,x)
Thanks a lot, this solutions seems to serve my purpose. A new method C.remove()
would of course be even better.
One could say the problem is solved, but why does there no method exist to
update a contour plot as there is for many other plot routines, i.e.
set_xdata/set_ydata for plot

I'm trying to plot several subplots. I have setup a scrollwidget and

Problem is that when I scroll, either some of the subplots are missing,

The pcolor function can take a vmin and a vmax parameter if you wish to
control the colorscaling. In addition, you can use a special array

Jeremy,
I believe that 0.99.1 is fairly old. I don't know when Axes3D came along,
but I am sure you can find it in 0.99.3. It is most definitely in 1.0, but
you might not need to go that far if your distro does not provide it.

I have successfully used ipython -pylab under w32 python, but under the
