Re: [Gnuplot-info] Set Linestyle bases on data value

[Aaron R. <aar...@gm...>]

This works for the most part:

plot DATAFILE using 4:1:5:(0):3:ytic(2)  with vectors notitle nohead lc
palette

but still wondering if there is a why to the the whole line style and not
just the color (so I could change widths or ps based on data)

Thanks.
