[Help] How to Change the number of samples X axis?

[Amer1233]

Please if any body can help me with this.

When FFT sampling frequency is 1000 [Hz] 

the x axis for first graph will have 200, the second will have 500 and the third will have 500 as well. Here is the question How could I decrease the samples for the first waveform from 200 to 1 ( 0.1 0.2 0.3 ... 1)Without changing the number of samples for other graphs.

Can you convert your Vi to LabVIEW 2020 ("save for previous") and attach it again?

[Amer1233]

To be honest I don't know how this could be done

I did but I'm still not sure if the alright or not.

You don't want to change the number of samples, just the x-axis scale (as I already mentioned in the other message:

(Right-click the graph terminal...create...property node...x-scale...offset and multipler...multiplier)

Unfortunately it didn't work.

Actually It did work now I got it. However the x axis is from 0 to 1. My goal to get 0.1 0.2 0.3 0.4 till 1 in the x axis.

You need to wire from the sampling frequency control, not from the data array.

Right-click the x-axis and change the formatting to show 1 decimal digits.

There are great training resources links at the top of the forum. Please use them!

(Who wrote the VI, it is a mess! For example I am not sure why you think you need to run two waits in parallel. In any, the longer one wins and the shorter one is irrelevant.)
