None that I know of. It would certainly be nice if we had the release 
package-building completely automated; or automated daily svn builds of 
the Win and OSX packages. Since I don't work with either Win or OSX, I 
don't know how hard this would be to set up.

Dang, I looked at it, but so much has changed since 0.98.3 release that I
have little chance of getting any changes implemented.
Any plans for a new release that you know of?
Thanks, Mark

The changes were in ticker.py and axes.py. Whether plugging in the 
current versions would work depends on the age of the other files you 
have. If you have a fairly recent svn build, then updating those two 
files probably would work. You could use svn to get the diffs 
specifically for my changes related to shared axes.

I noticed on the event handling doc page:
mat...@li...
that the draggable rectangle example doesn't work in version 0.98.3.
The rectangle class no longer seems to have the xy property. If you
replace the current on_press() method in the example with the code
below it seem to work.
 def on_press(self, event):
 'on button press we will see if the mouse is over us and store
some data'
 if event.inaxes != self.rect.axes: return
 contains, attrd = self.rect.contains(event)
 if not contains: return
 xy = self.rect.get_x(),self.rect.get_y()
 print 'event contains', xy
 x0, y0 = xy
 self.press = x0, y0, event.xdata, event.ydata

Thanks Manuel, and sorry for not forwarding it and being a little bit
"absent" these days

I was gone for the weekend (sorry, but that 'life' thing gets in the way of
getting things done sometimes). I don't have a way to build stuff at the
moment. Can I just check out the axes.py and replace my current one, or are
there too many changes?

Ah, seems to be fixed in 0.98.3 (but fedora f9 ships 0.91.2)

matplotlib-0.91
I got a nice semilog plot on the screen. Trying to save it to pdf fails, saying 'cannot take log of nonpositive value'.
