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

[theozh <th...@gm...>]

in case this is still of interest...
If the values in the 4th column are numbers, you could pick the RGB-value from a string.
Check for example `help linecolor variable` and `help word`

Hope this helps, Theo.
