Re: [Gnuplot-info] coloring points based on column value when also using hypertext labels

[Michael S. <Mic...@bo...>]

Theozh,

Thanks for the script.  I learned about some nice gnuplot features by
reading it and testing it.

Is there a way to associate hypertext with objects?  I would like to add
hypertext labels for the moon phases it

Thanks,
   Michael
