    return;
  }

  final Offset start =
      Offset.lerp(_oldPoints[0], points[0], animationFactor)!;
  final Offset mid = Offset.lerp(_oldPoints[1], points[1], animationFactor)!;
  final Offset end = Offset.lerp(_oldPoints[2], points[2], animationFactor)!;
  drawDashes(canvas, series.dashArray, paint, start: start, end: mid);
  drawDashes(canvas, series.dashArray, paint, start: mid, end: end);
