[Matplotlib-users] Update errorbar plot

[r-w <rzz...@gm...>]

I have been able to embed a matplotlib simple line graph into a wxpython 
application and then dynamically update the underlying line data.

However, I now want to do something similar with an errorbar plot.  I 
see that the errorbar() call returns (/plotline/, /caplines/, 
/barlinecols/) where 'plotline' describes the line part of the plot and 
the 'caplines' and 'barlinecols' describe the error bars and use the 
Path object.

I just can't see how to change the values underlying the errorbars.  I 
need to change the x and y values as well as the yerr values.

Anybody have any idea how to do this?  Or should I look at other 
approaches, such a simple line graph and a patch that draws error bars 
'by hand'?

Thanks,
Ross
