Hi,
I have a huge data set of impedance curves. I would like to be able to click on one line in a gui plot and get the corresponding information to that line.How would I do that?
Thanks a lot!

x = rand(10,1) ;
y = rand(10,1) ;
plot(x,y,'.r') ;
[px,py] = getpts() ; % double click on a point when prompts
text(px,py,'point') ;
But what you want to do is a bad idea.

That's actually not what I wanted to do, I want to get a Callback with the information to which data set this curve belongs. But I already found a way to do it I guess, let's see if it is working out.
Thanks for your suggestion anyway!
