Hi ,When I use matplotlib to draw 2D graphics in django web site，I encounter
a problem.
when server users use matplotlib to draw graphics simultaneously will
cause website collapse.
when one user use matplotlib to draw graphics will have no problem.
Is there an error / stack trace generated? Can you give an
example of how you are using matplotlib from django?
I can imagine there being some issue if you are using the pyplot
interface to deal with all user requests (e.g. plt.plot, instead
of allocating an axes object for each user and calling ax.plot).
There's no way for us to know unless you provide more details.
i suppose matplotlib doesnot support multithreading drawing.
so i put the draw function in a thread . it can't work as before.
I don't follow.
so why matplotlib doesnot support multithreading drawing?
How to solve this problem.
Depending on the load, the nature of desired plots, and the need
for user intervention, you might be able to get around the issues
you're having just by spawning a new process to do the plotting.
P.S.
I try to answer all of the questions I feel capable of answering
on the mailing list, there is no need to send duplicates of
mailing list questions directly to me.
best,
