Jouni:  That test script now crashes with:

Could somebody test that script with current trunk (rev. 7899)? I don't
have basemap installed, but I think my latest change might shake out the
bug.

Hi,

Running the simple attached test.py script creates a very simple  
test.eps. Converting this to a pdf file with ps2pdf causes the  
negative numbers to disappear (except the minus sign). Of course, the  
PDF backend can be used from the start, but there are situations (e.g.  
typesetting with LaTeX where one needs to include an EPS file, and the  
final document will be a PDF file, in which case the negative numbers  
disappear during the conversion). I have submitted a bug report:

https://sourceforge.net/tracker/?func=detail&aid=2883256&group_id=80706&atid=560720

Cheers,

Tom

I am +1 on that feature request. I don't have time to code it, though
:).

Hi,

one thing I missed when I switched from Gnuplot to matplotlib was that I
can't press "q" to close a window but have to use the window manager; in
one environment I work in that means I have to use the mouse to close a
window.

I made a custom key handler that does the following:

        try:
            event.canvas.manager.destroy()
        except AttributeError:
            pass

which seems to work, at least with GtkAgg (I didn't venture to find out
why the AttributeError is raised, it works in spite of that).

Would it make sense to have that shortcut by default (and working for all
windowing backends)?

Four shall be the number of spaces thou shalt indent, and the number of thy
indenting shall be four. Eight shalt thou not indent, nor either indent thou
two, excepting that thou then proceed to four. Tabs are right out.
