I just made a 2D scatter-plot with variable sized filled circles and varied
the fill color of the circles to encode for an additional fourth dimension
(using the gnuplot devel version again).
I used a predefined color palette for the color variation.
set palette rgbformulae 7,5,15
splot "data.txt" using 2:3:4:5 with points pt 7 ps var lt palette
I still cannot figure out how to include transperency for my fills though.
Transperent fills might alleviate some of my circle clash problems when
data gets clustered together.
I borrowed this from one of the demos but somehow it doesn't work.
set style fill transparent solid 0.5
Any sugesstions?
