[Matplotlib-users] Horizontal bar chart with log x-axis, no filled boxes
I'm running into something odd in Matplotlib 1.1. In drawing a horizontal bar chart (barh), if the x-axis scale is set to log, the rectangles are not drawn and filled; I just get small ticks at the right-hand position where the rectangle should end. Interestingly, if I add a second, stacked barh to the same axes, that second set of rectangles draws fine, even though the first does not. If I simply comment out the call setting the x axis to log, it works properly. Any thoughts? -- -- Christophe Pettus x...@thebuild.com -- RSA(R) Conference 2012 Mar 27 - Feb 2 Save $400 by Jan. 27 Register now! http://p.sf.net/sfu/rsa-sfdev2dev2 ___ Matplotlib-users mailing list Matplotlib-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/matplotlib-users

Does everything work correctly if it is vertical? In other words, use bar()
and set the y-axis to log scale? An example script would be useful.
No, it doesn't appear to work as a vertical bar chart, either.
I've attached a test case below. The results I get running it with the X-axis
as log are:

Commenting out the call to ax.set_xscale('log') gives me:

D'oh! Of course, I missed that tiny little detail. Hmm, so the
auto-detection would have been useless in this case because the scale of the
axes was set after the fact.
Maybe the log kwarg should be in a more prominent location in the docstring?
Moving the call to set_xscale('log') to before the calls to barh fixes the
problem nicely... thank you!

[Matplotlib-users] Figure area size questions
My apologies for two totally noob questions, but I can't quite seem to find these in the docs; a pointer would be great... 1. I would like to position a legend outside of the main plot area. The positioning part works great, but the legend is clipped to the pre-existing figure dimensions; how can I expand the figure size horizontally to allow for the legend? (And is there any way of auto-sizing the figure to include all of the stuff within it?) 2. In the horizontal bar chart I previously mentioned, the labels on the ticks on the Y-axis are clipped on the left side, as they are too long to fit into the pre-existing space. What's the best way of allowing more space for the tick labels, either by contracting the chart itself or expanding the figure?

In mpl v1.1.0, we introduced a function called tight_layout which should
help with such things. Admittedly, it would be nice if tight_layout did
something similar to bbox_inches='tight' and accept a list of additional
artist objects to consider, but it does not do that right now.
Both of those worked wonderfully... thanks very much!
