Displaying statistical data

Question

Hello,
  It's been a long time since I have not been on this forum or done any C# work by the way, so I just want your guidance concerning WPF.
Suppose I have a time series I want to display as a graph. With GDI and Winforms this is going to be rather easy: write a loop that scans the data and places a small icon representing a unit of data on the canvas at the appropriate place.

When I'm looking into WPF it seems to be designed for fixed screens at least that's the first examples you are given, now I want to know if you can get the directX advantages of WPF to display my dynamic kind of data. Do you have a tutorial that can help me?
thanks
Henri
