I just want combine three signals together then show in the graph, how to do that?(Not three separate waveform)
Solved! Go to Solution.

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

The waveform shows in graph is separated(3 sine waves), how to show a mixed waveform?

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.

But the waveform is different with the one I got by using Multitone Generator.vi,why
this is output from Multitone generator.vi

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

I attached my vi, please modified this , thank you

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.

Could you just modified based on my vi? beacasue i'm not quite know how to do what you said, thankyou

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