Hello everybody,

to reset data I'm using pylab.setp instead of the methods line.set_xdata,
line.set_ydata believing there would be no obvious difference in behaviour.
(Maybe I not really get what is going on in matplotlib.artist.py.)

The taken time is of quite big importance to me because I really often reset 
my data. That's why I set up a little program investigating the taken time 
using plot, setp, line.set_xdata/ydata ( I attached it).

The result really surprises me (using module time):
 time >plot<  9.7 sec
 time >setp< 9.9 sec    <- slower than plot!
 time >.set<  5.0 sec

So my question is: Is this the expected / desired behaviour?

best regards and thanks in advance for any hints,
Matthias
