solved: how to plot vco frquency with variation of control voltage

i designed cross coupled lc-vco with center frequency of 2.7 Ghz. i want to know how vco frequency varies with control voltage .for that which analysis i have to do..
please help...

You can do it from tran - with parametric sweep or simple graph in any spreadsheet.
Also it is possible to set control voltage as parameter in PSS, after simulation plot frequency directly from "Direct plot" form.
 
thanks for reply..
i have done the procedure what ever you told ..but after i got struck at which option i have to choose to get vco curve
here i am attached analysis window
