[Nplot-devel] Manual line drawing

[Dave C. <dav...@gm...>]

Nplot crowd,

I'd like to manually draw lines on a plotsurface. Said lines should be
pinned to start/end coords so that a resize will resize the line(s) too.
Purpose is trend and support/resistance lines for stock market charts.

Does anyone have code, clues or kludges they could share?

Thanks,
Dave Cline

I have something similar on my todo-list as well but haven't looked at it
yet.

As a starting point I would look at the RubberBandSelection class.
