The flat, black colored line should appear directly beneath the colored line. The black line measures the micro:bit acceleration. And the colored line measures micro:bit simulator acceleration.
A black line should appear directly beneath the colored line. The black line measures the micro:bit acceleration. And the colored line measures micro:bit simulator acceleration.
Run the acceleration experiment by vigarously moving the plate in any direction or move the object below the micro:bit (such as a table).

Second, the flat colored horizontal line will start moving to plot the value of the strength as measured in milli-gravities. The horizontal line's movement is based on the micro:bit acceleration in Magnitude or Strength.
