[syncfusion_charts] StackedColumnSeries fail without data #2172

Open DrNiels opened 1 week ago

DrNiels commented 1 week ago

Bug description

I'm using multiple StackedColumnSeries. Some potentially have no data. If that is the case, no series is displayed.

Steps to reproduce

  1. Load example
  2. See that there are no displayed values
  3. Remove the empty series by commenting it out
  4. See that the other series is displayed now

Code sample

Code sample ```dart import 'package:flutter/material.dart'; import 'package:syncfusion_flutter_charts/charts.dart'; void main() async { runApp( MaterialApp( home: TestChart(), ), ); } class TestChart extends StatelessWidget { @override Widget build(BuildContext context) { return SfCartesianChart( primaryXAxis: DateTimeAxis(), series: [ StackedColumnSeries( xValueMapper: (num value, int index) => DateTime(2000 + index), yValueMapper: (num value, int index) => index, dataSource: [], ), StackedColumnSeries( xValueMapper: (num value, int index) => DateTime(2000 + index), yValueMapper: (num value, int index) => index, dataSource: [1, 2, 3], ), ], ); } } ```
