    <!--...-->
</Charts:CartesianChart>

C#

public MainWindow() {

    this.InitializeComponent();

    // Create a series:
    Series series = new Series();

    // Specify the series view:
    series.View = new PointSeriesView();

    // Create a point collection and assign it to the series:
    PointDataCollection pointCollection = new PointDataCollection();
    pointCollection.ArgumentScaleType = ScaleType.DateTime;
    pointCollection.ValueScaleType = ScaleType.DateTime;
    series.Data = pointCollection;

    // Add points to the series:
    pointCollection.Add(new PointData(new DateTime(2022, 01, 01), new DateTime(2020, 02, 02)));
    pointCollection.Add(new PointData(new DateTime(2022, 01, 02))); // This point is empty. 
    pointCollection.Add(new PointData(new DateTime(2022, 01, 03), new DateTime(2020, 01, 02)));
    // Add other points.

    // Add the series to the chart:
    chart.Series.Add(series);

    // Specify x-axis settings:
    chart.AxisX = new AxisX {
        DateTimeMeasureUnit = DateTimeMeasureUnit.Day,
        DateTimeGridAlignment = DateTimeMeasureUnit.Day,
        SideMargins = 0.01,
        GridSpacingAuto = false,
        GridSpacing = 1
    };
