Re: [Matplotlib-users] DreamPie (a new Python shell) and matplotlib
The intended audience of IPython and DreamPie is, I think, quite similar. Perhaps DreamPie is more suitable for less computer-savvy people, as it is a GUI application and not a terminal-based one. I've seen that "ipython --pylab" goes to interactive mode by default, and has a %run command which runs scripts in non-interactive mode. Will a behavior like this be fine?

Re: [Matplotlib-users] DreamPie (a new Python shell) and matplotlib
I think the answer is yes (at least for me). A behavior like the one of ipyhton is fine. Eric, is DreamPie able to run parallel jobs like IPython or not ? If not, are you thinking to support a behavior like that ? I think it is very useful for trying to run parallel jobs interactively, most of all if you want to test MPI programs. 2010/9/6 Noam Yorav-Raphael : > The intended audience of IPython and DreamPie is, I think, quite > similar.

DreamPie doesn't support running parallel jobs. I don't plan to support such a feature in DreamPie - I actually think it should be the job of a shell-independent library. The job of the shell would be to let you interact easily with the library. Thanks for the feedback! Noam -- This SF.net Dev2Dev email is sponsored by: Show off your parallel programming skills.

[Matplotlib-users] Updating legends in dynamic plot
Hello,
I have a Qt4 application with dynamic embedded matplotlib plotting.
The application allows the user to add and remove lines from the plot.
This all works well, but I have found that updating the legend is
causing a memory leak. What is the proper way to update the legend in
an animated/dynamic context? The attached stand alone example
exemplifies the problem. On my system, with matplotlib.__version__
'1.0.0' compiled from SVN, the memory slowly increases as the script
runs. This does not happen if I remove the ax.legend() call. The del
ax.legend_ line seems to have no effect. I tried finding the artists
associated with the legend What's the appropriate way to update the
legend to avoid this behavior? I just found ax.legend_.remove() but it
raises NotImplementedError
Thanks,
Glenn

[Matplotlib-users] aligning multiple legends
I want to have two legends (from different axes) positioned right up against on another. Here's a static example, except I want the second legend to be defined relative to the first (if leg is moved, I want leg2 to move as well). I can't seem to figure out the proper bbox_to_anchor and bbox_transform parameters to pass to the second legend() to make this work. # small example ax = plt.subplot(1,1,1) ax2 = ax.twinx() ax.plot([0,1], label='ax1') ax2.plot([1,0], 'r--',label='ax2') leg = ax.legend(loc='lower left', borderaxespad=0, bbox_to_anchor=(.85,.85)) leg2 = ax2.legend(loc='upper left', borderaxespad=0, bbox_to_anchor=(.85,.85)) thanks in advance, Paul Ivanov -- This SF.net Dev2Dev email is sponsored by: Show off your parallel programming skills.

You may take a look at the legend guide. http://matplotlib.sourceforge.net/users/legend_guide.html For your original question, it is not possible to do that with the current legend implementation. However, you may put the legend inside the AnnotationBbox, which enables this. I'm posting the example for any future reference.
