Nils,
Perhaps the rectangle selector might be of use? It defaults to a draw mode
of 'box', but you can set it to line so that it looks like a ruler widget.
http://matplotlib.org/api/widgets_api.html#matplotlib.widgets.RectangleSelector
I can imagine that you could set up a selector callback that could then
query the data on the graph to "snap" the final line to the nearest points
on the graph, creating a Line2D object on the fly. Is that what you are
looking for?
Cheers!
