I'm just a begineer myself, but this is how I've accomplished this task in the past.
First of all, I was receiving my data as a 1-D array of waveform data. I wired this data to a 'build array' function inside a 'for loop' where I then spliced it into a 'build waveform' to combine it with a time value from the waveform data. I essentially just rearranged the data to a form that could graph all data simultaneously. The attached vi might help my explanation.
Hi, to show multiple plots on your waveform graph you have to organize them into array and connect to the node of the waveform graph in the diagram. 1. If you use numeric arrays to represent plots you have to collect them into 2D array (array of plots). 2. If you use waveforms to represent plots you have to collect them into 1D array of waveforms.
Please see the Waveform Graph.vi example in \examples\general\graphs\gengraph.llb. This example shows many different ways of plotting multiple plots on to a graph. As a general answer, to plot multiple plots on a chart, create a bundle where each plot is one item in the bundle. To plot multiple waveforms to a graph, build an array of waveforms where each array item is one plot.
