Plot coordinates with gradien colour according to a different column
Hi everyone, I'm having problems with plotting my data. I have a set of positions with different attributes and I'm wondering if I can plot it, as x,y plot, with gradient colours according to a 3rd factor. Is it possible to show gradient segments between postions and not one-coloured segment between each one? I've been trying plotrix color.scale.lines with no luck. I'm very thankful for any help!!
