Point-specific colors with scatter

Hi there,

I've got 4 time series that live in a 2-d space (imagine points at
(1,1), (1,2),(2,1), and (2,2) that drift a little over time), and I'm
using scatter() to show them. How can I plot so that each of the
groups of points has the same colour?

I've checked the docs and examples and can't seem to find quite what
I'm looking for. A sample script or indication of where to look in the
docs would be appreciated.

Many thanks!
Fred.

What you can do is something like this:

x = arange(4) # just some test-data
y = x**2

c = ['#ff0000', '#cc3300', '#996600', '#66cc00'] # the color sequence

pylab.scatter(x,y, color=c)

I think you get what you are looking for if you do this for each group separately.
