dataToPoint method

@override Offset dataToPoint(covariant dynamic angleData, covariant dynamic radiusData)

将给定的数据转换为对应的坐标点

Implementation

@override
Offset dataToPoint(dynamic angleData, dynamic radiusData) {
  num angle = _angleAxis.dataToAngle(angleData);
  num r = _radiusAxis.dataToRadius(radiusData);
  return circlePoint(r, angle);
}
