How to connect this

[LeoLiu]

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

[AdnanZ]

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

[LeoLiu]

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

[AdnanZ · Accepted solution]

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

[AdnanZ]

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

[LeoLiu]

I attached my vi, please modified this , thank you

[Broken_Arrow]

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.

[LeoLiu]

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.
