Add chart to the widget tree

Add the chart widget as a child of any widget. Here, the chart widget is added as a child of container widget.

@override
Widget build(BuildContext context) {
  return Scaffold(
    body: Center(
        child: Container(
          child: GraphTool()
        )
      )
  );
}

Note

• Use GraphTool widget to render line, spline, area, column, bar, bubble, scatter, step line, and fast line charts.

Bind data source

Based on data, initialize the appropriate axis type and series type. In the series, map the data source and the fields for x and y data points. To render a line chart with category axis, initialize appropriate properties.

@override
Widget build(BuildContext context) {
  return Scaffold(
    body: Center(
        child: Container(
          child: GraphTool(
            // Initialize category axis
            primaryXAxis: CategoryAxis(),

            series: <LineSeries<SalesData, String>>[
              LineSeries<SalesData, String>(
                // Bind data source
                dataSource:  <SalesData>[
                  SalesData('Jan', 35),
                  SalesData('Feb', 28),
                  SalesData('Mar', 34),
                  SalesData('Apr', 32),
                  SalesData('May', 40)
                ],
                xValueMapper: (SalesData sales, _) => sales.year,
                yValueMapper: (SalesData sales, _) => sales.sales
              )
            ]
          )
        )
      )
  );
}

class SalesData {
  SalesData(this.year, this.sales);
  final String year;
  final double sales;
}
