[Matplotlib-users] Selectable vertical lines

[V. A. S. <so...@es...>]

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
