Hi, I have a question for a simple problem.

When I plot two horizontal lines ,e.g.
plot([1 2],[2 3;2 3])
each line is by default coloured according to the current colormap definition. By default, the first is blue the second is green.

I would like to plot 'n' points, e.g.
plot(1:n,rand(1,n),'x')
and I would like them to be colored according to the colormap as well. I know how to solve this problem using a for loop. But I was wondering if anyone knows how to do this without a for loop?
