Hi,
The following code fails for me with matplotlib-0.90.0 –
axes.patch (559 Bytes)
···
import pylab as pl
x = pl.randn(1000)
pl.hist(x, orientation=‘horizontal’)
pl.show()
This is because Axes.barh() [called by Axes.hist() in axes.py] doesn’t accept the keyword argument ‘log’. The attached patch fixes the problem for my purposes (linear scaling of the axes) but obviously fails to scale the bin count axis correctly if hist() is called with log=True i.e. pl.hist(x, orientation=‘horizontal’, log=True).
It appears that this is still the case in the latest svn version of axes.py.
Cheers,
Scott

Scott,
In svn, barh does accept the 'log' kwarg via **kwargs, and your example works correctly. Here is the relevant CHANGELOG entry, after 0.90 was released:
2007-03-03 Change barh to take a kwargs dict and pass it to bar.
Fixes sf bug #1669506.
I think it was just a matter of changing the barh signature to:
def barh(self, bottom, width, height=0.8, left=None, **kwargs):
but I haven't looked back at the svn records to check that.

I see.
I only checked that the code in hist() hadn’t changed. I guess it pays to be thorough. Hope this didn’t waste too much time.
