[matplotlib-devel] FW: re-draw problem with FigureCanvasQTAgg in backend_qt4agg
Hi Sandro, I have $ python -c "import matplotlib as mpl ; print mpl.__version__" 0.98.5.2 Installed and am running PyQt v4.4.3 because I am forced to rest on Python 2.5 I will try installing 0.98.5.3 and see if that makes a difference. I have seen the same problem in a Unix installation, I will try and see which matplotlib version they were running. Meanwhile can you try re-sizing the dock widgets as fast as possible? If you use the mouse to re-size them but do it gradually, the problem does not surface. Thank you and I will see what happened with the new instalation -Original Message- From: matrixh...@gmail.com [mailto:matrixh...@gmail.com] On Behalf Of Sandro Tosi Sent: Wednesday, June 03, 2009 11:44 AM To: Alberto Soto Cc: matplotlib-devel@lists.sourceforge.net Subject: Re: [matplotlib-devel] re-draw problem with FigureCanvasQTAgg in backend_qt4agg Hi Alberto, On Wed, Jun 3, 2009 at 10:49, Alberto Soto wrote: > Good afternoon, > > I am working on a GUI that utilizes the FigureCanvasQTAgg.

Re: [matplotlib-devel] re-draw problem with FigureCanvasQTAgg in backend_qt4agg
Hi again, I have just installed matplotlib 0.98.5.3 and the problem seems to have been fixed. But the movements are a lot slower though, (probably because a lot more paint events were added?).

[matplotlib-devel] Curvelinear grid support
Jae-Joon, I just saw your curvelinear grid support fall into SVN. Very impressive! We actually may have a use for it here at Space Telescope for drawing "World Coordinate System (WCS)" plots. One quick question though -- it seems that this functionality is completely independent of the axes_grid stuff, which is primarily about layout out axes within a figure, correct? Is there a reason why it's part of the axes_grid toolkit that I'm missing?

And I tend to put everything that is not astronomy-specific into axes_grid toolkit, which may not be such a good idea. While one needs to use a custom Axes class (axes_grid.axislines.Axes) to support the curvelinear grid, this part of the code can be easily separated out. But I'm not sure if creating another mpl_toolkit package is best way to do here. Any suggestion will be welcomed.

It would be best if my algorithm does not produce such a case, but evidently it does. Yes, I'll put some code to treat this special case and also see if I can avoid such cases by improving my algorithm.
