Why the x axis dateTime start with 01-02-1980?

[gogommd]

I am using the DateTime set at x-axis, but the first value start with 01-02-1980 is not 28-03-2024. How to solve it?
The data's date is 2024-03-26 07:43:00.000

primaryXAxis:
  DateTimeAxis(
      dateFormat: DateFormat('''dd-MM-yyy\nHH:mm'''),
      title: const AxisTitle(text: "Date and Time"),
    ),

Hi @gogommd,

You can achieve your requirement with the help of DateTimeCategoryAxis in the SfCartesianChart. Date-time category axis is used to display the date-time values with non-linear intervals. We have prepared a workaround sample by setting the initialVisibleMinimum and labelPlacement to LabelPlacement.onTicks in the DateTimeCategoryAxis to always display the axis label from the given data point. We have shared code snippet, sample, screenshot, and user guide documentation for your reference below. Please let us know if you have any further questions or needs.

Code Snippet:

        primaryXAxis: DateTimeCategoryAxis(
            labelPlacement: LabelPlacement.onTicks,
            edgeLabelPlacement: EdgeLabelPlacement.shift,
            dateFormat: DateFormat('dd-MM-yyy\nHH:mm'),
            initialVisibleMinimum: DateTime(2024, 03, 26, 07, 43, 00),
          ),
          primaryYAxis: const NumericAxis(),
          series: <CartesianSeries>[
            LineSeries<ChartData, DateTime>(
              animationDuration: 0,
             dataSource: [
                ChartData(DateTime(2024, 03, 26, 07, 43, 00), 28),
            ],
              xValueMapper: (ChartData sales, _) => sales.year,
              yValueMapper: (ChartData sales, _) => sales.sales,
             markerSettings:  MarkerSettings(
                isVisible: true,
                color: Colors.blue.shade900,
              ),
            ),
          ],
