Dear all,
I was wondering if anyone can think of a neat trick to vary the color of 
a line according to magnitude. E.g. If I plot sin(x) I'd like the color 
to vary with signal matnitude.

To explain further what I am trying to do, I'd like to use a palette of 
greens and reds so that when the signal goes over a threshold then the 
plot would vary (slowly) from green to red to highlight specific issues.

Thanks very much, as always,
John
