Multiple and Combinational Charts

NOTE

Multiple and Combinational Charts only applicable for SfCartesianChart

Multiple series

You can add multiple series to the series property of the SfCartesianChart class. By default, all the series are rendered based on the PrimaryXAxis and PrimaryYAxis in SfCartesianChart. If you want to plot different unit or value that is specific to a particular series, specify separate axis for that series using the xAxisName and yAxisName properties of series.

dart

@override
    Widget build(BuildContext context) {
        return Scaffold(
            body: Center(
                child: Container(
                    child: SfCartesianChart(
                        primaryXAxis: CategoryAxis(),
                        series: <CartesianSeries>[
                            ColumnSeries<ChartData, String>(
                                dataSource: chartData,
                                xValueMapper: (ChartData data, _) => data.x,
                                yValueMapper: (ChartData data, _) => data.y
                            ),
                            ColumnSeries<ChartData, String>(
                                dataSource: chartData,
                                xValueMapper: (ChartData data, _) => data.x,
                                yValueMapper: (ChartData data, _) => data.y2
                            ),
                            ColumnSeries<ChartData, String>(
                                dataSource: chartData,
                                xValueMapper: (ChartData data, _) => data.x,
                                yValueMapper: (ChartData data, _) => data.y3
                            )
                        ]
                    )
                )
            )
        );
    }

Also refer multiple axes for customizing the axis further.

Combination series

SfCartesianChart allows you to render a combination of different types of series. In the following code snippet, the column and line type series have been combined.

dart

@override
    Widget build(BuildContext context) {
        return Scaffold(
            body: Center(
                child: Container(
                    child: SfCartesianChart(
                        primaryXAxis: CategoryAxis(),
                        series: <CartesianSeries>[
                            // Render column series
                            ColumnSeries<ChartData, String>(
                                dataSource: chartData,
                                xValueMapper: (ChartData data, _) => data.x,
                                yValueMapper: (ChartData data, _) => data.y
                            ),
                            // Render line series
                            LineSeries<ChartData, String>(
                                dataSource: chartData,
                                xValueMapper: (ChartData data, _) => data.x,
                                yValueMapper: (ChartData data, _) => data.y2
                            )
                        ]
                    )
                )
            )
        );
    }

Limitation of combination chart

• Cartesian type series cannot be combined with circular series (pie, doughnut, and radial bar).
