Problems with displaying high frequency sine wave

[Anis_toronto]

Hi all,
I don't why LabVIEW has problem with high frequency display.
Someone plzzz explane me how to see a better grapth on grapth?
check this function waveform generation.vi in examples go to search and type "waveform"
set the feq to 1k.

Thanks and regards

I think that this is related to LabVIEW, but more basically to the Shannon theorem 😉 : if you want to describe a periodic function, you need to take enough samples. First, expand the x scale to see a delta t of 0.001 s (ie a period of your 1000 Hz signal). Remeber to set the autoscale property on OFF. Then go to "sampling info" and increase the sampling frequency. See the result...
