I'm finding some really weird behavior in matplotlib that I just 
can't figure out.
When I plot out the following short script:
 >>> from pylab import *
 >>> y = [-48.0694,-48.0754,-48.0772,-48.0781,-48.0782,-48.0781,
 -48.0772,-48.0720]
 >>> plot(y)
 >>> savefig('bs.png')
I get a y-axis that goes from -10 to 0, instead of -48.0782 - 
-48.0694. And in the upper left hand corner of the plot I see the 
string "x1e-3-4.8069e1".
I'm running python 2.3.5 on Mac OS X 10.4.2. Matplotlib 0.82.
Any hints?

Confirmed here with matplotlib 0.84, GTKAgg backend, Fedora Core 4. 
Maybe the solution is simple: stop the mouse before releasing the 
button :-)

And for those running Fedora Core 4, which has a dependency of pygtk2 on 
Numeric and therefore installs the package python-numeric-23.7, I 
sort-of recommend building Numeric 24.0 from source ("python setup.py 
bdist_rpm") and then installing the resulting RPM with 
"--replacefiles". I haven't thoroughly tested everything, but so far 
this setup seems to work for me.

Hi,
there is something weird going on when zooming
(matplotlib.__version__: '0.85.cvs').
If I do
from pylab import *
x=arange(0.0,10.0,0.01)
plot(x,sin(x**2))
show()
and then choose the "zoom to rect mode"
it is possible to create, one after another,
several zoom boxes which are all visible and the interiour is not
updated, while the axes ranges are.
(Moving the mouse outside of the window with the figure
will update the plot.)
This seems to happen reproducibly,
when one zooms in such a way that
one release button1 while still dragging.
To be clear (hopfully):
one clicks with button1, keeps it pressed
and moves the mouse. While moving one releases button1
but continues moving.
Somehow the redraw for the inside is not issued
when the mouse is still moving but the button already released.
(Note that this is not an artificial problem, but
does happen a lot).
Is this behaviour reproducible on other systems/platforms
(I am running this on debian sarge with the default backend)?
Best, Arnd
