Hi, I hope somebody can advise whether this is possible, and if it is, then how.

I am plotting x-y data. I want to be able to click onto a x-y coordinate, and this click would enable a run of a script that would open/plot another figure.

In my case I am plotting eigenvalues (real and imag axis). I want to click on an eigenvalue and get another figure which would plot participation factors related to this eigenvalue.

Many thanks, Marina.

It could be hacked using datacursormode and a custom callback.

But you will probably find it easier to use a ButtonDownFcn axes callback (after having set the plotted lines themselves to HitTest off). The callback would need to figure out what was being clicked on and react appropriately.
