[syncfusion_chart] Daylight Saving Time not working as intended with daily interval

[DrNiels]

Bug description

When using a daily DateTime x axis that bridges a change towards Daylight Saving Time, the axis is not displayed correctly. On the one hand, the day with the change towards DST should be a bit shorter. On the other hand, the maximum of the axis is not shown, propably pushed out by an hour.

Similarly, a change away from DST does not show the day as longer and has an offset after the maximum of the axis.

It seems to me like the ticks are not positioned correctly and are just placed every 24 hours, which is not correct for these days.

I use syncfusion_flutter_charts in version 27.2.4

Steps to reproduce

1. Change your time zone to Germany (CET)
2. Load the sample
3. Look at the example
4. The top chart shows a change towards DST, not showing the last hour according to maximum
5. The middle chart is meant as a reference and does not have a change of DST
6. The bottom chart shows a change away from DST, with an offset to the right and the 27th shown twice according to ticks, probably 00:00 and 23:00 with 24 hours between dur to DST change

Code sample

Code sample

import 'package:flutter/material.dart';
import 'package:syncfusion_flutter_charts/charts.dart';

void main() async {
  runApp(
    MaterialApp(
      home: Chart(),
    ),
  );
}

class Chart extends StatefulWidget {
  @override
  State<StatefulWidget> createState() => ChartState();
}

class ChartState extends State<Chart> {
  @override
  Widget build(BuildContext context) {
    return Column(
      children: [
        Expanded(
          child: SfCartesianChart(
            primaryXAxis: DateTimeAxis(
              minimum: DateTime(2024, 3, 31),
              maximum: DateTime(2024, 4, 3),
              intervalType: DateTimeIntervalType.days,
            ),
          ),
        ),
        Expanded(
          child: SfCartesianChart(
            primaryXAxis: DateTimeAxis(
              minimum: DateTime(2024, 4, 1),
              maximum: DateTime(2024, 4, 4),
              intervalType: DateTimeIntervalType.days,
            ),
          ),
        ),
        Expanded(
          child: SfCartesianChart(
            primaryXAxis: DateTimeAxis(
              minimum: DateTime(2024, 10, 26),
              maximum: DateTime(2024, 10, 30),
              intervalType: DateTimeIntervalType.days,
            ),
          ),
        ),
      ],
    );
  }
}
