I'm working with Visual Studio 2015, C#, WinForms.

I just added a normal chart from toolkit and changed type to line, then added the following code:

```
chart1.ChartAreas[0].AxisX.LabelStyle.Format = "HH";
chart1.ChartAreas[0].AxisX.Interval = 1;
chart1.ChartAreas[0].AxisX.IntervalType = DateTimeIntervalType.Hours;
chart1.ChartAreas[0].AxisX.IntervalOffset = 0;
chart1.ChartAreas[0].AxisX.IsMarksNextToAxis = true;
chart1.ChartAreas[0].AxisX.IsStartedFromZero = true;
DateTime minDate = DateTime.Today;
DateTime maxDate = minDate.AddHours(23);
chart1.ChartAreas[0].AxisX.Minimum = minDate.ToOADate();
chart1.ChartAreas[0].AxisX.Maximum = maxDate.ToOADate();
chart1.Series[0].BorderWidth = 2;
for (int i = 0; i < 24; i++)
{
    chart1.Series[0].Points.AddY(i);
}

```

Output:

Why the chart isn't showing the points added?
