FabioNieVec commented 1 month ago

Bug description

If I zoom in with zoomMode: ZoomMode.xy, in a Stacked column chart. The chart will only show me the stack that is the highest and also the color. It also happens if you move above the 0 y point

Steps to reproduce

  1. Zoom the chart in with y > 0, x can be anything
  2. if you move the chart 0 y = 0 than you can the all stacks
  3. if you move up they will disappear

Code sample

Code sample ```dart SfCartesianChart( legend: const Legend( isVisible: true, position: LegendPosition.bottom, overflowMode: LegendItemOverflowMode.wrap), primaryXAxis: CategoryAxis(), zoomPanBehavior: ZoomPanBehavior( enablePanning: true, zoomMode: ZoomMode.xy, enableSelectionZooming: true), series: [ StackedColumnSeries( dataSource: chartData, xValueMapper: (ChartData1 data, _) => data.x, yValueMapper: (ChartData1 data, _) => data.y1 ), StackedColumnSeries( dataSource: chartData, xValueMapper: (ChartData1 data, _) => data.x, yValueMapper: (ChartData1 data, _) => data.y2 ), StackedColumnSeries( dataSource: chartData, xValueMapper: (ChartData1 data, _) => data.x, yValueMapper: (ChartData1 data, _) => data.y3 ), StackedColumnSeries( dataSource: chartData, xValueMapper: (ChartData1 data, _) => data.x, yValueMapper: (ChartData1 data, _) => data.y4 ) ] ) ```

Hi @FabioNieVec, @Trung15010802,

We would like to let you know that the reported issue is fixed and rolled out in our patch release. We kindly request you to upgrade the syncfusion_flutter_charts package to the latest version below.

Version: https://pub.dev/packages/syncfusion_flutter_charts/versions/25.1.42+1

Root cause: Stacked column/bar series rectangle bottom position was replaced with zoomed y axis minimum range instead of previously calculated bottom values.

Regards,

Preethika Selvam.
