How can I disable an frequent update of chart contents?

Hello,

I have a vi with a xy graph (x = time) and lots of data in there (aprox. 6000 values).

I do not update the values very often, maybe once in a second, to not to stress the cpu too much, but I have noticed, that the chart updates much more often and that causes a high cpu load. If I cover the VI with another window druing run time, the cpu load drops to almost 0.

Can I set how often a chart updates? Where?

Oh, I just found out, that my problem comes from somewhere else.

I set the xscale minimum and maximum every cycle according to the current time. If I reduce this xscale updates, the cpu time drops drastically 🙂
