Cantilever dynamic Analysis

I have designed a fixed-free cantilever for the detection of mass by shift in resonant frequency.A varied mass is applied on the free end of the cantilever. which will shifts its resonant frequency .when mass m1 is applied it gives resonant freq f1 and when m2 is applied it give f2  and so on. now i want to plot the graph of shift in resonant freq vs mass applied (e.g f1-fo, f2-fo , ........ Vs m1, m2 and so on)  

i got the resonant freq of (fo= 52966 Hz ). and frequency response under 1 uN force. 

Mass =7.31e-25kg . it can be varied from (1-300) just like (1* 7.31e-25, 2*7.31e-25..........300*7.31e-25)


I need this kind of graph from Ansys.  kindly guide me how can i do this. The .wbpz file is attached below in the comments.
