BaseMeter.getCoor

Usage

int getCoor(double v) const;

Description

Gets the geometric coordinates given the data value.

For an angular meter, this method returns the angular position of the pointer for the given data value in degrees. The angle is measure in the clockwise direction, with 0 being the upward pointing direction.

For a linear meter, this method returns the linear pixel offset of the pointer for the given data value.
