Re: coloring points based on column value when also using hypertext labels

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.

### point color depending on column value
reset session

$Data <<EOD
1   4   foo     1
2   3   bar     3
5   8   baz     2
EOD

set key noautotitle
myLabel(col) = sprintf("%s", strcol(col))
myColor(col) = int(word("0xff0000 0x00ff00 0x0000ff", int(column(col))))

plot $Data u 1:2:(myLabel(3)):(myColor(4)) w labels hypertext point pt 7 lc rgb var
