Plot Phase Noise Measurement

Hi,
I want to plot the Phase Noise Measurement. The measurement is got by a Electrical Spectrum Analyzer, which gives a CSV file with power and frequency values. I want to use the Leeson phase noise formula(is there any method?): L(f)=Pn(dBm/Hz)-Ps(dBm)-10log(RBW)

I am not sure if my code is correct. By the way, I would like to get a graph like what I attach. x-axis is frequency offset, that is, the frequency between fo and fm. y-axis is phse noise.

The span frequency is usually 2MHz. My graph starts at 2*10^3 Hz and it should start at 10^0 Hz.....

I attach MatLab file and csv file.
Thank you

I'm trying to plot power spectrum and phase noise using an inbuilt function
But, I'm not able to get the plot. Any help would be appreciated.
