matplotlib-devel Mailing List for matplotlib

Hi,
The PolyCollection class currently closes the path for each polygon by 
adding a last point the same as the first point. This means that the 
line joins will be different on this point. I've submitted a patch to 
make PolyCollection use Path.CLOSEPOLY to close the path, which makes 
the line joins on the stroking correct.
See https://sourceforge.net/tracker/?func=detail&aid=2890979&group_id=80706&atid=560722
There is also a small test script and the current and expected output 
attached to the above tracker entry.
Please let me know if there is some other way this should be fixed.
Best regards,
Matt.

I now think this is not the dpi issue.
Can you check the size of your figure in mac os X backend, after the
plot is drawn?
print f.get_size_inches()
8x6 inch is the default.
With dpi setting of 300 and bigger, the figure size (in pixel) will be
likely larger than your monitor size. And it seems that in mac os X
backend, the figure gets shrunken to fit the display, effectively
reducing the figuresize.
So, my recommendation is to use smaller dpi for screen display
(default is something like 80), and increase the dpi when saving the
figure ("savefig" has a dpi parameter).

Unfortunately, I still see the same behaviour using the latest version
from SVN. As noted earlier, I work around the issue now by switching
to the pdf backend.
