chart update rate

[LW42]

Hello,

I would like to create a vi containing a while loop, however I want charts data to be updated every second. Which is the proper way to do it so?

Thank you in advance

Hi,

You can make 2 states, wait and update. In wait state, you can put 1 sec delay and in update mode you can update chart.

I think this is the simple way. You can have another loop acquiring/generating data which you want to display on the chart.

I'm not sure to understand what you mean...

Is your while loop acquiring/generating data at more than 1Hz?

If yes, I assume you want to update the chart only each 10 or 100 loop iteration.

Here is a quick example (documented in LV 8.6).

Hope it help
