How obtain amplitude from energy distribution ? STFT

I have the input from a text file with the measurament of accelerometer and I use the STFT to have a graph with frequency vs time vs energy distribution. But I need the amplitude in the z-axis, how can i obtain it ?

The STFT diagram is an 2D array of z values.

dt and df are provided by the STFT vi  (dt usually already by the wfrm 😉 )

Index value of the 2D array ... done 🙂

I know what you said but i need to conver the energy distribution of the z axis with the signal amplitude
