That is what I was assuming, but it still seems a little odd that

Because the image is so large, and matplotlib carries out various
operations on the image (scaling, resampling, etc), it uses a lot of
memory. This is one area where a specialized display program will be
more efficient. If you need to use matplotlib, decide whether you

This is not how `show` is used. But

Hi,
I am writing a script that uses pyplot.show() to show a plot, on which
the user has to ponder and decide a course of action (telling the script
what to do on a raw_input).
I would be happy if the pyplot window does not "freeze" python below,
i.e. if the window can somehow exist while the pyth
I have a working system now. Here's what I did to fix it.
1. Installed libpng from source
2. Installed freetype2 from source
3. Installed pkg-config from source
4. Installed a new version of the Xcode developer tools for the mac.
During the build I still saw a few 'incompatible architecture' erro

Hi All,
my program lets slow down my cpu. This only appears if i plot to much
points. I am not sure how many point i need to get this, normally i plot
3*14e6 + 8e3, that is round about 50million points. My system is a
dual core 2GHz cpu with 2Gbyte Ram.
Here is my method to plot,

Hi Fabrice,
Good to hear that you were able to get it work.
Here is some tweak on transforms.
This way, the plot is shown correctly even if you change the y-limits of axes.
trans0 = blended_transform_factory(ax0.transData, ax0.transAxes)
trans1 = blended_transform_factory(ax1.transData, a
Try calling legend() again once you've changed the lines; in ipython -
pylab, this
x = linspace(-10, 10, 101)
sub = subplot(111)
plot(x, x**2, label="x^2")
plot(x, x**3, label="x^3")
legend() #Two lines, two legend entries
sub.lines[0].remove() #One line, two legend entries
s
Thanks Reinier,
For posterity ended up just doing the following:
matplotlib.interactive(True)
...
s = ax.scatter(data1, data2, data3)
draw()
s.remove()
s = ax.scatter(data4, data5, data6)
draw()

Hello,
I've been struggling with this for a while now and have effectively two
issues. One, how can I define the range over which hexbin ... bins? And two,
how do I change the background color of a plot? The latter I thought would
be trivial, but nothing I've tried has worked. Let's take the exam

I guess I don't have pkg-config installed. Is this a requirement? I haven't
had it installed before?

What does
pkg-config libpng --modversion --libs --cflags
give?
The pkg-config error may actually be a red herring, since matplotlib
will look in /usr/local even if pkg-config fails, and it obviously found
the headers or it wouldn't have gotten to the linking stage. As the

Hi Ryan,
This is currently not supported. Since also the 2D PatchCollection
does not support it I don't see how to easily add it either...

Hello,
I know how to remove a line from an axes. But a I also want to remove the
label of the line from the legend of the axes.
In the sample code you can see two labels in the legend, while there is only
one line in the axes left.
