Hi. A couple of questions about `scatter`:
Q1
====
The bounding box `axes.dataLim` increases in size when calling 
scatter(x, y) compared to plot(x, y) (for the same x, y data, of 
course). I think this change is due to the size of the markers being 
added to the data limits (not sure if this is true). Is there an easy 
way to get the same data limits I would have for a call to `plot`?
Q2
====
Is there a way to get the data from the axes of a scatter plot?
Initially I thought I could get it with:
 >>> for collection in ax.collections:
 >>> for path in collection._paths:
 >>> print path.vertices
But this seems to be the path that draws the scatter markers. Any ideas?
Frame Class
==========
Finally, if anyone is interested, I'm playing around with a Frame 
class for `axes.frame`. This class adds customizable axes frames 
similar to the topic of this thread:
http://sourceforge.net/mailarchive/message.php?msg_id=87d57vjgye.fsf%40peds-pc311.bsd.uchicago.edu
In this older thread, the SAGE axes frames were criticized for not 
being flexible enough. I've tried to make this class as general as 
possible (within my ability:). As an example of the flexibility of 
this Frame class, I've added some Tufte-style frames similar to:
http://hupp.org/adam/weblog/2007/09/03/etframes-applying-the-ideas-of-edward-tufte-to-matplotlib/
To the developers on this thread: If there's anything I could do to 
make the attached Frame class more flexible (and more suitable for 
possible inclusion into MPL), I'd be happy to get some feedback.
Current Limitations:
================
* the frame can only be placed on the borders of the axes (mainly 
because I don't know how to move the tickers anywhere else).
* RangeFrame only works with linear data (I'm not sure how to use the 
`axes.transScale` to properly transform the data)
* RangeFrame and DashDotFrame don't work properly with `scatter` 
(because of the questions in this post).
The frame class itself isn't too long, but I got a little carried away 
adding in extra crap.
Sorry for the long, rambling email.;)

If I understand you correctly, what I think you want are:
title()
xlabel()
ylabel()

Hello:
I am trying to diplay legend of X and Y axes like: legend(('label X', 'label Y'), isaxes=True)
and I get an error<type 'exceptions.TypeError'>: __init__() got an unexpected keyword argument 'is
axes'
How can I display labels for X and Y axes and a Title for the plot
Thank you,
Ionut

in Matlab, gcf() returns a handle to the last activated figure, either
by click or programmatically (e.g. "figure(1)", etc)

gcf is written to return the last figure activated or created by the
"figure" command. It would be fairly trivial to add support for
making the last clicked figure the active one, but it seems like a
reasonable thing to do (does anyone know what matlab does?). Since
gcf emulates a matlab function, I'd like to hew fairly closely to
that.

Hi all, 
I have a little problem, I've been unable to solve, maybe someone can help
me out.
I have several figures opened, but when I use gcf() I get handle of the last
opened figure instead of the active one... 
i.e. when intercepting a button_press_event, gcf().number returns the number
of the last figure, not the number of the figure over which I clicked
(different from last one).
How can I force that the gcf() to return handle to the active figure? 
Is there any event trigered when a figure gets the focus?
I don't think this should be the normal behaviour, but I have review my code
and I haven't found how could I be forcing this... any idea about how to
debug this? or if this is a bug?
some data that may help:
matplotlib version 0.98.1
interactive is True
units is False
platform is win32
numerix numpy 1.1.0
backend TkAgg version 8.4
