You must change over time the value of the variable.

Here is a modification of the code used by @SteveJG
Gauge_alt.aia (44.4 KB)

Edit:
App with extension com.KIO4_VUmeter.aix
Gauge_alt_v2.aia (55.9 KB)

Here with Canvas:

Try this works for me

SoundAnalyser2.aia (30.8 KB)

Note: Google Charts is probably not the best solution for what you want to do, due to the delay in updating the chart and the chart blinking when it does update. What is needed is an on device charting solution which will be offered by the upcoming built-in Chart component, or can be done now using the canvas, or by signing up to High Charts and using their javascript on the device.
