I am doing some work for which I need to develop a control, it should be a simple graph that shows several points and two edges.

My problem is that I need to show up to 16k points, with an update rate of 30 Hz. Has anyone done something similar?, and has any advice?.

For example whether to inherit from FrameworkElement or Control (ItemsControl in this case). If the control inherits from FrameworkElememt it may have a better performance drawing the points in the OnRender method but I would miss the Templating feature that comes from inheriting from Control.

Or does there exist another control that can do this out there?

Thanks in advance for your time.

    I ended up using InteropBitmap, it is the fatest bitmap rendering class from WPF.

    It allows you to map the image that you want to paint (in memory) and then reder it as a Image. This was perfect as i needed to plot points on the screen.

    I got great performance (almost 50Hz for 20k points), i also use PLINQ to update the points in memory.
