Re: [Matplotlib-users] line segments in a scatter plot
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!

Re: [Matplotlib-users] line segments in a scatter plot
Hi Ben, I have attached a sample scatter plot. The task is to add lines to the scatter plot.

Re: [Matplotlib-users] line segments in a scatter plot
I would just call use `plot` and keep track of the Line2D objects returned. On Thu Dec 11 2014 at 10:40:05 AM Nils Wagner nils...@googlemail.com wrote: Hi Ben, I have attached a sample scatter plot.
