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.

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.
Other su
may be you can try pyplot.ion()? it turns interactive mode on.
Hope this helps.

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()
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

hello,
have an error occuring that causes my app to crash. I found a few other email

I agree that
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.

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,

My guess is that the error happens when the matplotlib tries to format
the date ticklabels when the xlim is not correctly set, i.e., [0, 1]
in the example. But, I'm not sure what is the best approach here.
Werner, if there is nothing to draw (i,e, xlim is [0,1]), change the
xlim to some arbitrary

Your workaround worked perfectly! Thanks a lot!

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

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
