If you want to show the waveform all at once (like a scope has captured an entire waveform), use a Waveform Graph. If you want something scrolling, put the chart inside a for loop and outside of it wire the waveform to the Get Waveform Components, extract the Y array and wire that through the for loop to the chart. You could also get the dt from the wavform and wire that to a wait function inside the for loop and simulate the time it takes to capture the entire waveform.
