Hello,
I am trying to add some vertical lines into a matplotlib figure axes.
The idea is to detect when the mouse passes over those lines in order to displace them following the mouse if the left button is pressed.
I need some help to know the simplest way to proceed. Currently I am looking into matplotlib.patches and considering to use a Polygon or a Rectangle but perhaps that solution is overkill for a simple line. Is there any example about how to do it? I am not using the pyplot interface but instantiating myself the Figure, the FigureCanvas and adding the axes to the figure.
Thanks for your time,
Armando
What about using axvline with the picker argument?

I think axvline is part of the pyplot interface that I am not using.
However your link is going to help me a lot. I thought picking was restricted to patches, and I had missed Line2D is an Artist too with the same capabilities.

axvline is a pyplot function, but it is also a method of the Axes class.
So if you have an Axes in your Figure, everything is ok
