Unfortunately in my hands this function only seems to work for x shorter than 300 elements.

For example:

x = 1:301
color_line(x,sin(x),cos(x))

never generates a plot(i.e. the plot window never refreshes.)

For x=1:300 it works beautifully though.
Is there a simply way to make it work for longer x (e.g. 2500 points).
