Re: [Matplotlib-users] cannot plot in loops with matplotlib 0.99. 0.98 works fine
Any idea why there is such a difference between 0.98.5.3 and 0.99 ?? Drawing the whole figure once, when no further Python input is available, is much more efficient than drawing after each plot() command. For some figures, matplotlib 0.98.5.3 becomes extremely slow. Thanks JJ, but unfortunately this is not the solution. draw() gives the same result. - and I am running this as a script (running it from ipython shell). The problem in your script is that the event loop never kicks in. Unfortunately, Python has no support for event loops in general, which makes this hard to solve. One option is to use raw_input() between calls to plot(), but then each time you have to hit enter to get the script to proceed. --Michiel. --- On Mon, 9/7/09, tva t...@brygge.dk wrote: From: tva t...@brygge.dk Subject: Re: [Matplotlib-users] cannot plot in loops with matplotlib 0.99. 0.98 works fine To: matplotlib-users@lists.sourceforge.net Date: Monday, September 7, 2009, 3:17 AM Thanks JJ, but unfortunately this is not the solution. draw() gives the same result. - and I am running this as a script (running it from ipython shell).

Re: [Matplotlib-users] cannot plot in loops with matplotlib 0.99. 0.98 works fine
Hi Michiel thanks, but does that explain why the script works smoothly in 0.98.6 and earlier versions? Plotting all the curves at the end of the script is certainly possible, but it is a severe reduction of the functionallity. given the fact that it works so well in earlier versions of matplotlib, it seems like a bug in matplotlib...?

Problem solved. The backend was set to Qt4Agg. Once set to TkAgg everything works.

I think an explicit call of draw() in the interactive mode (e.g. with ipython -pylab) should update the figure canvas immediately. And this is the behavior I currently observe with Gtk and Wx backend. If the Qt4 backend behaves differently, I guess this is a bug. I don't have the qt4 backend installed, and I hope other developers take a look. -JJ -- Let Crystal Reports handle the reporting - Free Crystal Reports 2008 30-Day trial.
