Plot live data in a TChart

Hi.

I plot live data in a TChart.
It should always only the last 10,000 values remain stored.
Older values should be deleted.

How to do this ?

When I plot values to the chart for many hours it will need to much memory and the computer will be very slow :-(

Many thanks.

Best Regards
Mandi
