Simulating signal over a range of frequencies

[imp_domi]

I have generated a sine wave with Simulate Signal and would like to analyse it over a range of frequencies and plot the result in a separate graph. I am wondering how I could use a for loop to scan the different frequencies automatically and not put the specific values in the front panel?

It depends what you mean by range of frequencies. If you want them linearly spaced, you can generate them with the "Ramp Pattern" VI.
