Plotting points with different colours

asked 2013-01-11 03:58:31 -0500

I'm trying to plot a number of points such that each has a colour that depends on a certain parameter. I have two lists, points and heights, and I would like to do something like this:

for i in range(len(points)):
    point2d(points[i], rgbcolor = (0,0, heights[i]))

This creates len(points) different graphics, so it's not what I want. What do I need to change?

Do you need something like:

sum([point((x,sin(x)),rgbcolor=hue(sin(x)),size=30) for x in srange(0,10,0.1)])

Yes! I would have never guessed `sum` does it. I guess I do not really understand what a point object is. For example, if I want to add a `polygon()` to the same plot, how do I do it?

If p1 is any plot and p2 a polygon then do: p1+p2

OK, I see how it goes. Thanks again.
