What exactly are you trying to measure? A temperature vs. frequency plot sounds like you want the temperature of your circuit vs. the input frequency, which I don't think is possible in Cadence.
You can get Frequency vs. Temperature, though. Temperature in Cadence is the temperature around the system. On the output you can then use the frequency function on a waveform, as dick_freebird mentioned. You can then change temperature with a parametric sweep by making the temperature a variable and using Tools -> Parametric Analysis. This will generate a Frequency vs. Temperature graph.
Hope this helps!
