[matplotlib-devel] Adding custom interactive backend
Hi, I have a modified version of the TkAgg backend, with a few custom features, and would like to be able to get pylab/matplotlib to use it, but without having to put the backend code into the matplotlib code tree. Is there a way to make matplotlib find and use a "backend_.py" which does not reside in matplotlib/backends/ , and without filling in entries in matplotlib/__init__.py and matplotlib/backends/__init__.py ? Thank you very much. Regards, Urvashi - This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML. No limits. Just data.

[matplotlib-devel] SaveFig bug in TkAgg backend
Hi, When the "save" button is used on the matplotlib tkagg toolbar, it uses the "Tk" "asksavefilename" object from the "tkFileDialog" class, to pop up a little window that allows you to select the name and type of file to save.This function internally calls "figure.destroy()". and the currently active figure gets destroyed (but it is still visible and memory is not freed). The next plot then creates a new figure window with the same figure._num as the previous. see... backend_tkagg.py : line 621 -> class NavigationToolbar2TkAgg :: def save_figure(...) (callback for the toolbar.bsave button) The "asksavefilename" function call, triggers Gcf.destroy(). This can be seen by placing a print statement in _pylab_helpers.py : line 16 -> class Gcf :: def destroy(num) A script to trigger this is attached Does anyone else see this, and does anyone have a way to fix this ? Thank you very much !
