Hi @BonyYeah,

We have checked the reported issue and attempted to replicate it using the SfCartesianChart with ColumnSeries. However, we were unable to reproduce the issue in the syncfusion_flutter_charts package to latest version https://pub.dev/packages/syncfusion_flutter_charts/versions/28.1.38.

However, we have ensured the scenarios mentioned with the latest version but are unable to replicate the issue.

1. Ensured with windows, web and android.
2. Tested with all axis type for primaryXAxis
3. Tested with one data point and tried with empty points.
4. Tested by setting minimum and maximum range.

We recommend you upgrade to the latest version, and if you are still experiencing the issue, we request you to replicate it in the attached sample and provide us with more details regarding the specific scenario in which you encounter this issue. This will help us to assist you more effectively.

Regards,
Aswini S.

Hi @AswiniDileep
Thank you for you reply! I used your sample to test, it doesn't appear, but I changed the CategoryAxis to DateTimeAxis, and set the minimum and maximum, also the data list only one data, it appear what I met first. Here is my code:

final List<ChartData> chartData = [
      ChartData("2024-01-01 00:00", 35),
    ];
    var minAxisDate = DateTime(2024, 1, 1);
    var maxAxisDate = DateTime(2024 + 1, 1, 1).subtract(Duration(days: 1));

    return Center(
      child: SfCartesianChart(
        primaryXAxis: DateTimeAxis(
          labelRotation: -20,
          minimum: minAxisDate,
          maximum: maxAxisDate,
          plotOffset: 12,
        ),
        primaryYAxis: NumericAxis(
          maximumLabels: 5,
        ),
        series: <CartesianSeries<ChartData, DateTime>>[
          ColumnSeries<ChartData, DateTime>(
            dataSource: chartData,
            xValueMapper: (ChartData data, i) {
              return DateFormat('yyyy-MM-dd HH:mm').parse(data.x ?? "");
            },
            yValueMapper: (ChartData data, _) {
              if (data.y != null) {
                return data.y;
              }
            },
          )
        ],
      ),
    );

And the screenshot:

I'm looking forward to your reply. Thank you!
