Re: [Matplotlib-users] idle and ipython and axis

I have experienced the same problem with IDLE.
It only works with -n, but then you lose the nice feature of 'starting
over'.
Does anybody know a fix so we can do both?
Thanks,
Mark

BTW, when you use pylab in interactive mode, the axis() command should scale
your figure interactively, also under IDLE. Have you tried that?

Yes, I tried using axis in both IDLE and IPython. IPython's redrew  
the axis automatically whereas IDLE's did not.

I am not sure, but I think this difference in behavior is b/c IPython  
is a bit better about calling draw_if_interactive after "most pylab  
functions" (see Eric Firing's http://www.mail-archive.com/matplotlib- 
us...@li.../msg02037.html) than IDLE is.

I too would LOVE to have the ability to start over as IDLE w/o the -n  
allows. Unfortunately for me (on a Mac) I've not yet been unable to  
use WxAgg w/matplotlib using Mac-available packages. I might be able  
to use it after I'm done following http://projects.scipy.org/ 
pipermail/numpy-discussion/2007-January/025368.html, but I'm in  
crunch-mode at the moment, so that install is going slowly.

No, this isn't it.  pylab does the draw_if_interactive call, and it is
called by pylab.axis:

def axis(*args, **kwargs):
    ax = gca()
    v = ax.axis(*v, **kwargs)
    draw_if_interactive()
    return v

I noticed in your subsequent post that interactive is set to True in
your rc file.  Make sure you are not running from the matplotlib
install directory or it will pick up your directory specific
matplotlib rc file.

You might want to do

  >>> from matplotlib import rcParams
  >>> print rcParams['interactive']

from within your IDLE session to verify.  Does interactive updating
work with other pylab commands.  I would be very surprised if just
'axis' were failing.
