John, I just tried all backends I have on my Win7 system (Qt4Agg, WXAgg, TkAgg) and found none of them could allow the animation in the line_editor.py. Please let me know whether I have to use GTK or GTKAgg to get the animation. Thanks.

I have tried running your attached example and it seems to run fine on my system (I can drag the vertices and the line drawing is updated). Can you describe the problem you are seeing? Could this be a version problem -- what version of mpl are you running? jo...@udesktop191:Downloads> python -c 'import matplotlib; print matplotlib.__version__' 1.0.svn > I read the Curse implement which uses lines.

It does use the animated property -- at least in the svn version. See the line in the __init__ function: if useblit: lineprops['animated'] = True JDH ------------------------------------------------------------------------------ ThinkGeek and WIRED's GeekDad team up for the Ultimate GeekDad Father's Day Giveaway.
