You need to use the Convert from Dynamic Data node and then build the array. Look at the attached screenshot

Well, double-click on Convert from Dynamic Data and choose '1D array of scalars - automatic' for all three of them. Then, right click on build array and make sure Concatenate Input is checked.

Can you post your original VI? I can then tell you what you might be doing wrong.

I think maybe you want a Chart, not a Graph, and use Bundle which will show three thinks at once, as opposed to combining three things. You got what you get based on your original question.

Multitone generator does a sum of the waveforms. Replace the build array with a compound arithmetic and add all three.
