Hi Stoyan,
I had this problem, refer to
http://sourceforge.net/mailarchive/forum.php?thread_name=1315605880.26850.7.camel%40GARDEN&forum_name=matplotlib-users
It was dismissed as a code error (which I would perhaps dispute).
You have two options:-
- Adopt the approach seen here:
http://matplotlib.sourceforge.net/examples/user_interfaces/embedding_in_qt4.html
- Or use the work around:
import matplotlib
# Free memory
matplotlib.pyplot.close()

Hi, my name is Stoyan.
??? I use the following packages: python 2.6 , PyQt 4.8.5-1, numpy 1.6 and matplotlib 1.0.1. In my program Matplotlib library I have used a GUI application created by "PyQt". In the program there is a loop that updates a graph by calling:
?self.fig.canvas.draw()
?? But every time the graph is updated, the memory usage goes up.I the address listed bellow there is an explanation of the reason for the issue however, even though
Fixes a memory leak where each spines' path was a view of the spine path by mdboom · Pull Request #89 · matplotlib/matplotlib · GitHub?
?? I have followed all instructions that have been specified in link,there is still a flaw in the programme due to a memory leak, though not a big one.?? I wondere whether there is alternative way to discharge this leak of memory and if so could you assist in solving it.
