Hey Stéfan,

To avoid the overlap on the titles and ticks, you will want to play
with the font size of the ticks and title, but most importantly the
subplots_adjust parameters hspace and wspace.
If using a suptitle, you may also want to adjust top.

Eg,

# you can also click on the "subplots adjust" toolbar icon to play with the
# settings to get something that looks right and then hard code this
fig.subplots_adjust(hspace=0.4, wspace=0.4)

for ax in ax1, ax2, ax3, ax4:
    ax.title.set_fontsize(11)
    for label in ax.get_xticklabels() + ax.get_yticklabels)():
        label.set_fontsize(9)

You can also use rc parameters to control the defaults:

Thanks for the advice, I'll play around with those parameters.

I was surprised that this works fine under Linux, so I tried switching
to the PDF backend on OSX, and now everything renders perfectly.
Could it be that the MacOSX backend does something strange?

Re: Layout of subplots in output

Stefan,

Can you try to install matplotlib again, after removing old ones.
The mac os X had a bug that does take care of the dpi. But I guess
this bug has been fixed in the svn.

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.

Re: Layout of subplots in output

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).

Closing paths in PolyCollection

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.

Bug in Interactive Save with WX Backend

Dear all,

I hope this isn't considered gauche, but:

A few weeks ago, I added a bug [1] I had found when saving figures from 
the toolbar with a WX-based backend.  I think it's a simple issue, and I 
included the simple fix that worked for me.  Since then there's been no 
apparent activity on it.  Is there something more I need to do on it?

If someone is already taking care of it, I apologize for hassling you. 
But if the fix is as simple as I think it is, it would be a shame to 
have it fall through the cracks.

Thanks,
Robert

Re: Incorrect output from demo_text_path.py on mac

Thanks for the report.
And I wonder if you can provide us some more details of your
configuration and do some more tests.

1) You're not using usetex mode, correct?

2) Does your mathtext work fine otherwise? I mean, with the ordinary
text command, not the textpath example.

Regards,

-JJ
