Efficient Real-Time X-Y Plotting/Graphing

I'm working on an application that graphs data for given time intervals. For example, I could be collecting data in real time, and i'm graphing the last 5 minutes of the data up to the current point. When I have multiple axes, the number of points for each axis can become large fast. I have to go though and process all of these points every time I update the graph. When I have points that are in a pattern, or straight line, it doesn't make since to keep all of the ones in the middle. Does anyone know of any algorithms/data structures to efficiently process a large number of coordinates?

BTW, I'm developing in C#.

Thanks!
