This attribute specifies the angle subtended by the sweep of the needle from MINIMUM to MAXIMUM along the arc. The value of SWEEP ANGLE can vary from 1 to 359 degrees.
Use this attribute to position the METER within its window. The METER widget uses an autoposition algorithm that positions the "meter movement" based on the specified WIDTH, HEIGHT, and SWEEP ANGLE attribute values. The needle pivot point, needle length, and centering of the arc within the window are positioned automatically.
