In PSS, direct plot of harmonic frequency gives single frequency - i need range!

Hi,
I'm simulating injection locked oscillator, i want to plot the relation between the control voltage and the output frequency.

I know that pss is not the best choice for that but i found this solution:

"For such oscillators you shouldn’t be using the Oscillator button in the PSS form as this is considered a driven circuit since it is driven by an injection source. That is the reason you are receiving the error message. Once you set the PSS form accordingly, set the tstab to 100 periods (and can also use the saveinit button to save the initial transient waveform before steady state). You should now be able to run the simulation."

Then i set-up the pss as follows:

Finally, this what showed up to me.

It's a single frequency. I need to see how the frequency vary while changing the control voltage.
Any help?!

Thanks in advance.
