Graph Populated by a Collection, and Colors

[User (Legacy)]

I'm creating a graph to be populated by points added from a series. This

collection will change though (think of it as a very slowly updating live

graph), and I find that when I redraw the graph, the color of the line

changes. I can force the line to a color, but in practice I will have up to

24 lines being drawn. Is there any way to bind a collection to a particular

color or series?

Many thanks,
