To split a waveform into two parts from a threshold with different colors on the same graph in LabVIEW, you can use the attached VI.
How to Use
First, acquire your waveform data and pass it into the Get Waveform Components "data" input. Then, 1. Checking if the signal's 'Y' component is higher than the Threshold, if so it should add that value or add a 'dt' time interval into the Build Waveform Y component input array, which will build a new waveform on the top of the threshold. After cutting the waveform from the threshold, it merges the 2 waveforms into one.
