Hi I'm using the .NET Data Visualization Toolkit to create charts in WPF. My application basically adds a new value to the chart every second and redraw the chart. The problem is that I only want to display 100 points on the x-axis at any given time but the chart seems to redraw itself with all the values. Is there a way to display a setup number of values on the x-axis using the charts in the Data Visualization Toolkit. If I'm unclear with my explanation you can look at the performance monitor built inside windows, thats basically what I'm trying to accomplish in WPF.
