Re: [matplotlib-devel] Layout of subplots in output
Hi JJ 2009/11/2 Jae-Joon Lee lee.j.j...@gmail.com: 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. It says [4, 2.52], so I think you are right! 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). This fixes the problem. Now, why does the MacOSX end do this when none of the others do? Thanks for helping me track this down! Stéfan -- Come build with us!

Re: [matplotlib-devel] Layout of subplots in output
Hi JJ 2009/11/1 Jae-Joon Lee lee.j.j...@gmail.com: 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. Regards Stéfan -- Come build with us!

Re: [matplotlib-devel] 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).

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: http://matplotlib.sourceforge.net/users/customizing.html JDH -- Come build with us!

on the screen, but comes out quite different when you save it?
I narrowed the problem down to this line:
matplotlib.rc('figure', dpi=300)
Does it do some magic behind the scenes?
Attached is the script that produces this:
Stefan,
You forgot the attachment.
dpi is an inherently confusing parameter because it can relate to font
rendering and to the resolution of an image. So there are different
kinds of dpi, but the distinction between them is not kept clear in the
code--at least it wasn't the last time I looked into this, quite a long
time ago.

Hi all, When saving plots (using plt.figsave and matplotlib from SVN) consisting of subplots, the layout is a bit messed up. As an example, have a look at http://mentat.za.net/refer/segmentation.pdf I have tried adjusting the figure size, the font size, the w- and hspace, etc. Is this a known problem, or am I doing something silly?
