Hi,
I've installed matplotlib (v 0.87.6_0) via macports (os x
10.4.8,
python 2.4.3). I've tried following the
"interactive" instructions at
matplotlib.sourceforge.net/interactive.html, which tells me
to modify
matplotlibrc as follows:
interactive : True
backend : TkAgg
My general usage is via ipython -pylab, which should
automatically
setup the necessary extra thread for plotting, but I've seen
similar
behavior in vanilla python shells as well.
I can run matplotlib commands (e.g. plot([1,2,3])) but plot
windows
are never shown (even after I explicitly call show()). I can
save the
figure and view it as a pgn, so much is working.
When I configure matplotlibrc via the rec'd TkAgg backend, I
get the
following error:
Traceback (most recent call last):
File "/opt/local/bin/ipython", line 28, in ?
IPython.Shell.start().mainloop()
[snip]
File
"/opt/local/lib/python2.4/site-packages/matplotlib/back
ends/
backend_tkagg.py", line 8, in ?
import tkagg # Paint image to Tk photo
blitter
extension
File
"/opt/local/lib/python2.4/site-packages/matplotlib/back
ends/
tkagg.py", line 1, in ?
import _tkagg
ImportError: No module named _tkagg
A google search led me to believe I didn't have "the
proper tcl-dev/
tk-dev" directories. I then noticed
there was a +gt2k macports matplotlib variant, and found
another
search snippet that led me to believe
installing this new variant might relieve my woes.
No such luck.
Has anyone gotten matplotlib to plot figures interactively
in the
macports/python24 setting?
Advice greatly appreciated.
