I would just call use plot and keep track of the Line2D objects returned.

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.

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!

Hi all,
how can I create line segments between consecutive selected points of a
scatter plot in an interactive manner ? It should be possible to create
several unclosed polygonal lines. Each polygonal line might have
a different color.
A small example is appreciated.
Thanks in advance.
