How to change the waveform graph from time domain to frequency domain?

[sheikh_zubi]

Even after doing FFT it shows time domain graph

You just need to label it as frequency. See clearly the time axis after FFT. Is it represent time or frequency values or bin number. If it is bin number, multiply that with your frequency resolution df, then you will get exact frequency of that bin. Post your code here, so that we will see and help you.

hi there

i am new user to LABVIEW and having same problem. All i can see in Graphs options are TIME DOMAIN graphs.

I have a Array of PHASE and want to show that phase response on Frequency graph. So, Frequency (x-axis) and degree (y-axis).

I have no idea how to do it. Can you please explain here step by step so that i will follow them.

Regards

Use an XY graph instead of a waveform graph - a waveform graph displays time-series data where the dt between points is the same. If you use an XY graph you can plot any combination of X & Y values against each other.
