To use matplotlib interactively from the prompt, you need a special
|
||
|
|
interpreter that doesn't enter the gtk mainloop. One is provided in
|
||
|
|
examples/interactive.py. The coew functionality of this interpreter
|
||
|
|
was provided by Brian McErlean and John Finlay. See the header for
|
||
|
|
more info.
|
||
|
|
|
||
|
|
This will only work if you have pygtk compiled with threading. See
|
||
|
|
instrubtions below.
|
||
|
|
|
||
|
|
WIN32 Users
|
||
|
|
|
||
|
|
I haven't tested the interactive shell on win32. It is apparently
|
||
|
|
possible, but not easy, to get threading to work on win32. See
|
||
|
|
http://www.async.com.br/faq/pygtk/index.py?req=show&file=faq21.003.htp
|
||
|
|
|
||
|
|
LINUX/UNIX Users:
|
||
|
|
|
||
|
|
To compile pygtk with threading, I recommend you make a backup of your
|
||
|
|
existing pygtk install tree and completely remove it
|
||
|
|
|
||
|
|
eg
|
||
|
|
> cd /your/path/to/python/site-packages
|
||
|
|
> cp -a gtk-2.0 /some/backup/dir
|
||
|
|
> rm -rf gtk-2.0
|
||
|
|
|
||
|
|
This is because I have found that recompiling pygtk with threads on top
|
||
|
|
of an existing installation w/o threads does not enable threads. Your
|
||
|
|
milage may vary.
|
||
|
|
|
||
|
|
Then from a clean pygtk src tree
|
||
|
|
|
||
|
|
> ./configure --enable-thread # and any other flags
|
||
|
|
> make install
|
||
|
|
|
||
|
|
TESTING threading
|
||
|
|
|
||
|
|
To test whether this install worked, try running this script
|
||
|
|
|
||
|
|
import pygtk
|
||
|
|
pygtk.require('2.0')
|
||
|
|
import gtk
|
||
|
|
|
||
|
|
import threading, time
|
||
|
|
|
||
|
|
def func():
|
||
|
|
n = 0
|
||
|
|
while 1:
|
||
|
|
print n
|
||
|
|
n += 1
|
||
|
|
time.sleep(0.1)
|
||
|
|
|
||
|
|
gtk.threads_init()
|
||
|
|
threading.Thread(target=func).start()
|
||
|
|
gtk.mainloop()
|
||
|
|
|
||
|
|
|
||
|
|
|
||
|
|
If it spits numbers back at you, you're golden.

TESTING with matplotlib
|
||
|
|
|
||
|
|
You should be able to make a simple plot with
|
||
|
|
|
||
|
|
> cd examples
|
||
|
|
> ./interactive.py
|
||
|
|
Welcome to matplotlib.
