Waveform Chart refreshment

Hello,
unfortunately i didnt find anything on this subject using the forum search (certainly because it is extremely simple to answer and i shd find it by myself 😉 )
But is it possible to make the refreshment rate of Waveform Charts visible in Labview? And does it set itself to the highest rate possible if not told otherwise?

thank you a lot

Your question is not very clear. Can you explain your concerns?

 

Your chart gets updated whenever you write to the terminal. If this occurs in a regular loop, you just need to measure the loop rate and there are many ways to do this (here is one).

 

Instead of trying to measure the loop rate, is it better to enforce a certain known loop rate, for example by placing a suitable delay inside the loop. If DAQ is involved, the loop rate is often determined by the configurations.

 

Also note that the actual update rate of redrawing the chart is probably slower because indicator updates are asynchronous by default for performance reasons.

 

You should also make sure that the chart itself does not slow you down. Don't set a GB chart history, for example.
