The question is unclear.
The problem seems easy enough,
if you get your hands on the arguments to your script.

Does nobody have an idea; especially for the 'dynamic'
number of plotted arrays!?
Regards!

Hi,
pylab.scatter(x,y)
pylab.errorbar(x,y,yerr,linestyle='None')
if you want to use scatter, or alternatively:
pylab.errorbar(x,y,yerr,fmt='o',linestyle='None')

Hello,
I was wondering where I can get an example of a scatter plot with error 
bars.
I have time measurements and the stds
0 23 0.23
1 25.1 0.21
4 27 0.1
7 29 0.21
9 35 0.1
how can I get a scatter plot with error bars? I know I can get a bar 
plot, but I need just a symbol with error bars.
Thank you,
Armen

Yes, that is pretty good, and much better
than the approaches used in the examples
behind the screen shots:

Thanks!
