of the two channel labels on the screen.
 absBB: the chord length of the crossing point of cursor XB and cursor YB relative
to the center point. The center point is defined as the crossing point of the the
horizontal position (namely the V axis) and vertical position (namely the Y axis)
of the two channel labels on the screen.
 argAA: the angle between the X axis and chord AA (the distance from the
crossing point of cursor XA and cursor YA to the center point). The range is from
-180° to +180°. The value is positive in the counterclockwise direction and
negative in the clockwise direction.
 argAB: the angle between the X axis and chord AB (the distance from the
crossing point of cursor XA and cursor YB to the center point). The range is from
-180° to +180°. The value is positive in the counterclockwise direction and
negative in the clockwise direction.
 argBA: the angle between the X axis and chord BA (the distance from the
crossing point of cursor XB and cursor YA to the center point). The range is from
-180° to +180°. The value is positive in the counterclockwise direction and
negative in the clockwise direction.
 argBB: the angle between the X axis and chord BB (the distance from the
crossing point of cursor XB and cursor YB to the center point). The range is from
-180° to +180°. The value is positive in the counterclockwise direction and
negative in the clockwise direction.
