addPositionToDetailsForSeriesDatum method

@override DatumDetails<D> addPositionToDetailsForSeriesDatum(DatumDetails<D> details, SeriesDatum<D> seriesDatum)

Adds chart position data to details.

This is a helper function intended to be called from getDetailsForSeriesDatum. Every concrete SeriesRenderer needs to implement custom logic for setting location data.

Implementation

@override
DatumDetails<D> addPositionToDetailsForSeriesDatum(
  DatumDetails<D> details,
  SeriesDatum<D> seriesDatum,
) {
  final bounds =
      _getRendererElement(seriesDatum.datum as TreeNode<Object>).boundingRect;
  final chartPosition = Point<double>(
    (isRtl ? bounds.left : bounds.right).toDouble(),
    bounds.top + (bounds.height / 2),
  );
  return DatumDetails.from(
    details,
    chartPosition: NullablePoint.from(chartPosition),
  );
}
