speed of plotting A/D inputs with stripchart

I use 12 analog input channels of DAQpad-6020e and plot them with a stripchart in an infinite loop but the ploting rate is very slow.

Hello;

At every new point that comes to the chart, the Labview user interface thread redraws the front panel. That might suck to much CPU time for that task, slowing down the whole application.

The best way to do that is to store a set of points and only update the chart from time to time, as opose to do it at every new point that comes along.
