matplotlib-devel Mailing List for matplotlib

a few comments:
One possible limitation of the proposed relim code is that it doesn't take
into account whether the lines are set visible or not. But otherwise it is
a useful function for interactive use, which incidentally is the way I use
matplotlib the most. 
Is there any reason why matplotlib doesn't have an optional additional
menubar ? You could fit far more commands than in a toolbar. 
btw as demonstrated by the qt4_editor it is not difficult to implement a
line properties dialog in matplotlib.
A feature-set that MATLAB has and is missing from matplotlib is editing the
plot via the GUI. You can actually remove lines from the plot without typing
anything in the interpreter. I think it is via a line properties menu, but
maybe you can also get there by right-clicking the line and choosing delete
(can't recall, I'll have to check).
If/when we add support for such things in mpl, the relimit button would
become much more useful.
Until we have that, I think JDH's idea for cross-GUI configurable toolbars
is a better target to aim for.

On a different but related topic, I think it would definitely be
desirable to support customizable toolbars, so users could easily add
their own buttons, remove buttons, connect them to their own
callbacks, etc... That would take a bit of work to handle this across
GUIS and platforms with icon specifications, etc, but would certainly
be useful. Adding one more button for a somewhat specialized use case
is definitely not a good idea, as only a tiny faction of users
actually modify data in objects in place.
A related button to autoscale y after zoom based on current x limits
would be somewhat handy in my own experience, but again, I'd rather
have customizable toolbars with a stock functionality that we could
add or remove as desired.

First, I am asking if there are no use-cases for this button in the future
with the advent of an improved ipython environment? In other words, more
people may use matplotlib+ipython like a regular MATLAB environment. Could
this button be a useful feature later?
Second, irregardless of whether this button is included or not, there have
been app developers who have added buttons to the toolbar for their own
use. Can these developers count on that real estate to always be free? Can
we definitively say that matplotlib will never have more buttons added to
its default toolbar?
Does that make more sense?

Ben,
I don't understand either of your questions. What's the point?

Just playing devil's advocate here...
Considering how we can now have multiple show() calls and with the upcoming
ipython looking more and more spiffy, could there be a future use case for
this toolbar button?
On the other hand, how would the inclusion of this button impact users of
other interactive scripts that have added their own buttons? I mean,
planning for the future, can it be definitively said that matplotlib will
never add anymore toolbar buttons? Could developers rely on that real
estate not being taken over by rule of "eminent domain", if you will?

I don't think it would. The standard toolbar is for typical interactive 
use, where I don't think the relimit functionality is needed often 
enough to justify having its own button--if at all. Better to keep that 
toolbar simple.

Hi,
I'm using matplotlib embedded in my wxpython application and needed to
give users a quick way to relimit a figure, for example after removing a
line from a plot. Therefore I added a button to the toolbar. Do you
think it would make sense to include this in matplotlib by default?
Appended you find modifications of backend_bases.py and
backends/backend_wx.py as well as a draft for a symbol. 
Greetings,
Dieter
