Measure amplitude continuously

Hi,

I am acquiring a sine wave, square, triangle wave with different frequencies and amplitudes directly into labview showing the result in a waveform chart continuously.

The thing is that i Want to display an indicator that shows the frequency and amplitude of the given waveform.

I have searched for point by point VIs, but there are no point by point VIs that measure amplitude or frequency of a signal.

How can i solve this problem?
