How to change pic.(power_1) to pic.(power_2)?

if you want to do that you can't use a waveform you have to use XY an graph. Only XY Graphs can have plots that have many Y value for the same X value.
Hope this helps

With the XY graph that was suggested, you can see an example here: http://zone.ni.com/devzone/cda/epd/p/id/2207

Thank you for your help, but I use ' the FFT power specturm.vi' to make the waveform ,so I can't get the X and Y value.
I holp to get more help, Thanks again !

Well of course you can get the Y array and then you can easily build the X array base on the To and dt.
Let me know if you need help to do that.

Thanks so much, can you give any examples for it.
Use FFT power specturm.vi to get X(amplitude) and Y(frequency) .

YES I need your help for that

All you need to do to get the X array is to use the Ramp Pattern function. In your case you'd want the Ramp by Delta instance since you have a t0 and a deltaT.
