[Gnuplot-info] TkCanvas; using tags for interactivity

[Mstislav E. <m_e...@us...>]

Hi All,

I am using the TkCanvas device to plot a number of series with lines
and of course would like to distinguish between different
series. However, the number of lines is large enough (about 30) to
make varying line styles impractical for identification. I would like
to be able to identify the series interactively using the mouse,
e.g. clicking a series should print its title.  The TkCanvas provides
support for some interactivity in form of the user_gnuplot_coordinates
procedure. However, its use is too complicated for my purpose. My idea
is to assign a tag to each series and use it for identification. Now
is there a way to pass the tag to gnuplot and have it attached to the
series? Maybe it is possible to repurpose the 'title' argument?


Thanks for any tips! Best

Mstislav
