Re: [Matplotlib-users] Plotting with more than two y-axes (with twinx?)

2013-11-28 Thread dodermat 
Joe's guess was right, I got identical IDs for all twinx().

I had OSX10.9, matplotlib 1.3.x and tried both Python 2.7 and 3.3. A friend
of mine has Win7, matplotlib 1.2.0 and Pyhton 3.3, and also encountered the
problem I described. Even the comments by Damian and Lunayo on Joe's snippet
in Stackoverflow indicate that they had the same issue.

I renewed all my package installations in order to get matplotlib 1.3.1 and
have an environment that is similar to Dale's. Now I get the proper output
with both Python 2.7 and 3.3. Problem solved - yet not understood...


Thank you for your help!

Re: [Matplotlib-users] Plotting with more than two y-axes (with twinx?)

2013-11-27 Thread Joe Kington 
Hi Daniel,

For what it's worth, the code runs perfectly for me as-is on matplotlib
1.3.1 with python 2.7 on linux.

However, based on your description, I'd guess that the second call to
`twinx` is returning the same axes object.

What happens when you do:

print id(axes[1]), id(axes[2])

Are the id numbers the same or different?

If they're the same, there may have been a regression/change that causes
`twinx` to return the same object instead of creating a new axes.

Cheers!
-Joe

[Matplotlib-users] Plotting with more than two y-axes (with twinx?)

2013-11-27 Thread dodermat 
Dear all

What I want to accomplish was produced two years ago in  a stackoverflow
snippet by Joe Kington

 
, and shown in the first figure below. However, when I use his snippet in
matplotlib 1.3.x, I get an output where the third axis replaces the second
axis, and the blue dots are accordingly distributed in only the lower half
of the plot (see second figure below). I considered downdating to an older
version of matplotlib, but then I came across  a remark in the matplotlib
FAQ   .
According to this remark, such a feature for twinx is on the wish list and
thus not very likely to be available in an older version.

Can someone please explain the Kington magic to me?
