Using mpl 0.98.5.2 in OO mode with wxAgg backend.
I'm trying to make my legends draggable. It works, but
there is a some inaccuracy with positioning. As I drag it,
the cursor "outruns" the position of the legend, and that

Once you have seen this example (+the picking), you are able do whatever
you want ;)
You have python, you have the best toolkit I konw (qt4 with qtdesigner)
and you have a very nice way to plot 2D data.
What else ;)

Hi, everyone,
I am a matplotlib beginner. I am trying to do a chart with 2 y axes using
twinx()
I keep getting error message "malformed header from script. Bad header=
is masked in one or more l: test.cgi" when I do two bar charts on two
axes. if I do one bar chart and one line chart, I wouldnt
I have been trying to install matplotlib under various versions of python.
I was able to get it installed in a 2.4.2 version, but, attempts to install
it in 2.5.3 and 2.6.1 have run into the same problem, that being the inability
of the setup script to locate numpy and freetpye2, both of which a
I hope to see the project on the web. I'm very intersting by simple
examples using mpl with PyQt.

John and Eric,
Thanks for your responses. I think I can do what I want with your suggestions.
As for the reason I wanted to know this: I found that when I placed a pdf
image created with matplotlib into Adobe Illustrator and then shrunk it down to
fit into my poster that the edges of my plot

Chris,
Maybe it is new, but
Hi folks,
Is there an OO way to get pyplot.axhline() ?
I found Axes.hlines, but it's not as convienent for doing a quick
horizontal line all the way across the axes: I need to specify the x coords.
thanks,

Wow, right there in the FAQ.
That worked great! Thanks for kindly pointing me in the right direction.

something like "fig.subplots_adjust(left=0.2)" would work.

Or if you're using PIL,
pil_image = PIL.Image.fromstring("RGB", im_size, buf)
I am trying to generate plots where the y-axis major tick labels are
date/times. My tick labels are getting cut off. How can I set a
larger area on the left to allow room for my entire date time stamps?

Hi,
I want to convert the current figure to a numpy array w/o saving the
image to disk. I need this to convert a matlab function to python, the
original code is:
F = getframe(gcf);
X = frame2im(F);
My current workaround is
h = gcf()
h.savefig('tmp.pn
