Create Charts
Live Chart Screen
All connected channels can be plotted (and logged) on charts in real time.
The plotting is Started, Stopped, or Cleared for all devices simultaneously with the same set of buttons.
The app will continue to run in the background* for seamless data collection even with the phone in your pocket.
Collected data can then be saved in Log files using the Save button (see below).
*We advise closing other apps if possible when collecting data in the background, because Android will close background apps if memory is low.
