The goniometer settings can be found in the preferences menu. Here you can adjust the appearance and functioning of all goniometers at once. All settings are saved and reloaded next time you open the app.
Time rage and amplitude range affect the visible range of data. For an uncalibrated device an amplitude of ±1 is the full scale maximum. However if you calibrated your device to a defined level of your hardware environment you might observe values above that range if clipping occurs (in that case you should decrease the gain/level of your hardware and calibrate again).
You can also enable the coordinate system and the trigger function that automatically finds onsets, which stabilises the graph for periodical signals. In that case you can greatly improve readability and overall usability of the goniometer. However, if you are analysing speech recordings or music you should turn the triggering off.
