continously and waveform graph

[fred]

Hi!

In my program Im recieving sampled data from hardware
via COM port.

If I want to display the data (voltage values) in
"realtime", continously, Is it possible to use
"waveform graph"? It seems to me that only "waveform chart" can be doing that. Can "waveform graph" only handle "finished" arrays(finished means "loop is done" and no more data to enter the array)?

The reason I ask this is that I want to have a correct timeaxle according to samplerate from hardware.

To be able to have correct time between the plots I am maybe forced to read data a certain time and when this time is reached the array is done and I can use the "waveform graph with bundle"?

Thanks Fredda

A waveform chart is used to append te data as it is acquired, the graph collects the data and then graphs it at the end. And yes you can collect your data and then output it to a graph when you are done sampling.

This link tells the differences in slightly more detail, hope this will help you out.
