I use:
plt.gca().get_frame().set_linewidth(2)

The Axes object has a method for turning on the frame: set_frame_on(). 
How do I set the thickness of the frame that appears?
Thanks,

Maybe with something like self.axis.axes.get_yaxis().get_view_interval()?

Is it possible to do animation with contour plots? How?

Hi everyone,
I am defining my own Locator class to determine where matplotlib 
should place the ticks on the x axis. I have managed do so, except 
for one problem. In order to determine the position of the ticks on 
the x-axis, I not only need the x axis range, which I can retrieve 
with self.axis.get_view_interval(), but I also need the y-axis range, 
or at least the y position of the x-axis. Is this something that can 
be done, and if so, how?
Thank you for any help!

Hello Anton,
I just had the same problem and came up with the following solution:
a = csv2rec(fname) # read a csv file into a
a[a.dtype.names[5]] # access column 6 (index 5) in the file 
As a shorthand you could assign the column names to another field in the
recarray:
a.cols = a.dtype.names
a[a.cols[5]] # access column 6 (index 5) in the file 
Hope this helps, even though it may not be good coding practice. I am a
novice myself...
Best regards,
Thomas

Thanks Jouni! This is exactly what I was looking for.:)

hello,
is there a way to make a 2d scatter plot that includes (outside the axes)
histograms of the marginals of the two variables? like the matlab function
'scatterhist'. see this for an example:
http://www.mathworks.com/access/helpdesk/help/toolbox/stats/index.html?/access/helpdesk/help/toolbox/stats/scatterhist.html
ideally i'd like the histograms outside the scatter plot to also have axes
so that the height of each histogram bar will be interpretable.
thank you
