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. -- View this message in context: http://matplotlib.1069221.n5.nabble.com/line-segments-in-a-scatter-plot-tp44602.html Sent from the matplotlib - users mailing list archive at Nabble.com. |

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!

Hi Ben, I have attached a sample scatter plot. The task is to add lines to the 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 <ni...@go...> wrote: > Hi Ben, > > I have attached a sample scatter plot.
