How can I see better the harmonic order of this plot?
Is it possible to have the FFT time in the form of frequency?
If yes, how do I go about that?

Hi

To change the X-axis quantity, right-click on the graph title and select Modify Report. Then, uncheck the current X-axis option and click on “...”, then choose a different quantity from the list.

Another option is to modify the X-axis properties. to do this, double-click on any axis in the graph and go to the 'X Axis' and 'X Scaling' tabs to adjust the settings.

I'm still having trouble understanding. I initially set my frequency as a function of speed, using the formula: Frequency * 120 / 26. Here, 26 is the number of poles. However, I didn't specify any units when I defined the frequency. The value I used is 60, not 60 Hz, so that when I define it based on speed, I get rpm.

I want to see the harmonic order of my machine design. Harmonic magnitude vs Frequency.
