Methods in Flutter Pyramid Chart (SfPyramidChart)

PixelToPoint

Converts logical pixel value to the data point value.

The pixelToPoint method takes logical pixel value as input and returns a chart data point.

NOTE: The method will return the center value of the segment.

//Initialize the series controller
PyramidSeriesController? seriesController;

@override
Widget build(BuildContext context) {
  return Container(
    child: SfPyramidChart(
      onChartTouchInteractionDown: (ChartTouchInteractionArgs args) {
        final Offset value = Offset(args.position.dx, args.position.dy);
        final PointInfo<dynamic>? chartpoint = seriesController?.pixelToPoint(value);
          },
