You don't mention how much data you will have at that point. It you are going to display it all, someone has to keep it, and the graph and shift register isn't quite as well suited to incremental updates as a chart (that is why the chart was written), but when you change properties on a chart, you often cause it to remap and redraw all of the data. Plus, you don't have direct access to the data in the chart. If you truly have lots of data, you may want to decimate it for the display. If you have numbers, I can give you some expected results.
