I have a large log file which contains data for 5 days, every second data is sampled. When I tried to plot the data in the xamDataChart, it's hard to read for a specific second, what the value should be, even I zoomed it to the largest. So I am thinking to let the user choose the period they want to plot. Can I do this simply change the xamDataChart's start and end point? So I don't need to change the ItemSource to bind to different collection.

Thanks,

Joan
