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.

Hi all,
how can I create line segments between consecutive selected points of a

several unclosed polygonal lines. Each polygonal line might have
a different color.
A small example is appreciated.
Thanks in advance.

Thank you for the fast reply, according to you line and "line," shouldt make

i tried the code with line and line, and it only works with line, ?
so you say if i use

Hi,
I'd like to plot experimental data points with fitted data through it. This
time best would be to plot hollow circles for the experimental data. Pretty

Is this possible somehow?
