[syncfusion_flutter_charts] [question] scroll a fixed width chart

[Macacoazul01]

Bug description

I need a way to set a defined width to my chart and if it is bigger than my screen size to turn it into scrollable (or to create a scrollable chart by default).

Saw the sample on cartesian-charts but only with the auto scrolling option and i need the same behavior with fixed data:

Steps to reproduce

Just create the bellow sample and run it on different screen sizes. On smaller sizes it will be hard to see the chart content as it will resize to fit on the new avaliable space.

Code sample

Code sample

```dart SfCartesianChart grafico() { final dataSouces = conteudoGrafico(); return SfCartesianChart( plotAreaBorderWidth: 0, legend: const Legend( isVisible: true, position: LegendPosition.bottom, overflowMode: LegendItemOverflowMode.wrap, ), primaryXAxis: const CategoryAxis( labelIntersectAction: AxisLabelIntersectAction.multipleRows, majorGridLines: MajorGridLines(width: 0)), primaryYAxis: NumericAxis( axisLine: const AxisLine(width: 0), numberFormat: NumberFormat.compactSimpleCurrency( locale: const Locale('pt', 'BR').toString()), majorTickLines: const MajorTickLines(size: 0)), series: [ ColumnSeries( animationDuration: 500, dataSource: dataSouces[0], xValueMapper: (ModeloGrafico sales, _) => sales.x as String, yValueMapper: (ModeloGrafico sales, _) => sales.y, name: 'Entradas', color: const Color.fromRGBO(3, 155, 0, 1), ), ColumnSeries( animationDuration: 500, dataSource: dataSouces[1], xValueMapper: (ModeloGrafico sales, _) => sales.x as String, yValueMapper: (ModeloGrafico sales, _) => sales.y, name: 'Saídas', color: const Color.fromRGBO(198, 0, 0, 1), ), ColumnSeries( animationDuration: 500, dataSource: dataSouces[2], xValueMapper: (ModeloGrafico sales, _) => sales.x as String, yValueMapper: (ModeloGrafico sales, _) => sales.y, name: 'Perdas', color: const Color.fromRGBO(250, 225, 2, 1), ), ColumnSeries( animationDuration: 500, dataSource: dataSouces[3], xValueMapper: (ModeloGrafico sales, _) => sales.x as String, yValueMapper: (ModeloGrafico sales, _) => sales.y, name: 'Transferências', color: const Color.fromRGBO(201, 31, 174, 1), ), ], ); } List> conteudoGrafico() { List listaEntradas = []; List listaSaidas = []; List listaPerdas = []; List listaTransferencias = []; for (final mes in mesesDoAno) { listaEntradas.add(ModeloGrafico( x: mes, y: 10, )); listaSaidas.add(ModeloGrafico( x: mes, y: 10, )); listaPerdas.add(ModeloGrafico( x: mes, y: 10, )); listaTransferencias.add(ModeloGrafico( x: mes, y: 10, )); } return [listaEntradas, listaSaidas, listaPerdas, listaTransferencias]; } ```

Hi @Macacoazul01,

You can achieve the scrollable chart when the screen resize by setting AutoScrollingDelta value based on available width. Then enable ZoomPanBehaviour with enablePanning as true. We have attached the sample below for your reference. If you have any further queries, please get back to us. We are always happy to assist you.

Sample: gh_2009.zip

@ThilipChandru tks for the sample, this solves my problem!

I would like also to suggest changing the parameter name as the current one is misleading.

If this isnt possible, please feel free to close the issue
