collecting correct frequency

[ZeeKay]

Hello, I'm doing a program that collects a voltage signal and I have problems getting it to display the correct frequency. In order to display a continuous input I created a circular buffer. I tried tapping my frequency signal as shown below: 

I was able to get the correct amplitude display but not the frequency. I tried tapping the frequency from other points (i.e. before the buffer) but it doesn't work. Does anyone know what should I do?

Why would you expect to get the correct frequency? You are not acquiring the signal with any timing information and this is required for the tone measurements function. Change to waveform data type which has the dt information. You could also modify the dynamic data type but I don't see any point in ever using dynamic data.
