You could also do this with function graphics by plotting with symbols and using the vert_colors keyword to provide your z vector.
Off the top of my head...
P=plot(x, y, symbol='o', vert_colors=z, rgb_table=39)
Syntax may be slightly wrong as I'm quoting from memory but should hopefully give the right idea.
This obviously only comes out as a line if you have a lot of data points.
