Re: [Matplotlib-users] histogram question

I wrote the following code to do this for me...it is not entirely general (in the sense that it doesn't accept all kwargs beyond bins and hatch) and also allows me to do my own normalization But you should be able to use it pretty easily. def open_hist(arr,bins=10,norm=None,hatch=None):

Re: [Matplotlib-users] Histogram orientation

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. Cheers, Scott >>> Eric Firing <[EMAIL PROTECTED]> 4/30/2007 20:02 >>> Scott, In svn, barh does accept the 'log' kwarg via **kwargs, and your example works corr

Re: [Matplotlib-users] Histogram orientation

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 c

John, Thank you for your thorough and thoughtful reply. OK, I am convinced. I had not realized that the present line-drawing code actually is omitting nonpositive points, but now I see the Line.get_plottable() method. I have committed changes to svn that I think will be helpful--maybe good en
