The Table control accepts a 2D array as an input. If you use a Waveform Graph (not chart), it is pretty easy. You can just build the two arrays into a 2D array (using Build Array) and pass it to the display. However, since a chart updates with each iteration, you cannot easily build it into a 2D array. If your graph is inside a loop, you could pass the data outside of the loop while building an array through auto-indexing.
Can you tell me more about what you are trying to do or upload a screenshot of your code?
