[Matplotlib-users] Galde example and Log scales

[Michael T. <Mic...@s3...>]

Hi,
	does anyone have an example of how to use matplotlib with glade2?

Any idea when log scaling will be supported?

Thanks, Michael

Hi,
	thanks for that example, I've been using the article from the Linux
journal "A begnners guide to using pyGTK and Glade",
http://www.linuxjournal.com/article.php?sid=6586, although I have been
using python for a while, and I ahd to make a small change to 

/usr/lib/python2.2/site-packages/matplotlib/backends/backend_gtk.py


try:
        import pygtk
        pygtk.require('2.0')
except:
        pass

I'm running redhat 8.0 and have these versions of pygtk installed.

[root@arne root]# rpm -qa | grep pygtk
pygtk2-1.99.12-7
pygtk2-libglade-1.99.12-7

Thanks, Michael

PS log scales by next week sounds great, take me at least that long to
sort out the rest of the stuff I need.

Thanks for the info.  matplotlib officially requires pygtk-1.99.16
which is where the require('2.0') thing comes from, but this has
caused a number of redhat users a lot of grief so I need to make the
changes you suggest to backport to earlier versions.  I'm curious to
know if with these changes all of the demos run on the default RHL8
install.  If you get a chance to run a number of them, let me know and
I'll update the web page.

Hi,
	the following seem to work,

arctest.py
axes_demo.py
stock_demo.py

but all generate similar errors along the lines of

Thanks for the info.  I can't replicate the warnings on my system
because I don't have the older pygtk installed, but if I an find an
appropriate test machine I'll see if I can find the source.

Oops, this was a bug introduced when I changed the color handling in
the abstract drawing interface.  In older versions of matplotlib, rgb
tuples were specified as 0-255 ints, now they are 0-1 floats.  It's
now fixed in CVS.  Thanks for catching it.
