Why does date ColumnSeries<DateTimePoint> not align?

[XavierJ96]

Hi,

My data columns does not align center of my XAxis. How do I fix this issue?

    public ISeries[] Series { get; set; } =
 {
    new ColumnSeries<DateTimePoint>
    {        
        Name = "Bar 1",
        Values = new ObservableCollection<DateTimePoint>
        {
            new DateTimePoint(new DateTime(2026, 3, 1), 3),
            new DateTimePoint(new DateTime(2026, 4, 1), 6),
            new DateTimePoint(new DateTime(2026, 5, 1), 20),
        }
    },
    new ColumnSeries<DateTimePoint>
    {        Name = "Bar 2",

        Values = new ObservableCollection<DateTimePoint>
        {
             new DateTimePoint(new DateTime(2026, 3, 1), 3),
            new DateTimePoint(new DateTime(2026, 4, 1), 6),
            new DateTimePoint(new DateTime(2026, 5, 1), 20),
        }
    },
    new ColumnSeries<DateTimePoint>
    {        Name = "Bar 3",

        Values = new ObservableCollection<DateTimePoint>
        {
              new DateTimePoint(new DateTime(2026, 3, 1), 3),
            new DateTimePoint(new DateTime(2026, 4, 1), 6),
            new DateTimePoint(new DateTime(2026, 5, 1), 20),
        }
    },
};

    // You can use the DateTimeAxis class to define a date time based axis 

    // The first parameter is the time between each point, in this case 1 day 
    // you can also use 1 year, 1 month, 1 hour, 1 minute, 1 second, 1 millisecond, etc 

    // The second parameter is a function that receives the value and returns the label 
    public Axis[] XAxes { get; set; } =
    {
    new DateTimeAxis(TimeSpan.FromDays(30), date => date.ToString("MMMM"))
    {
         LabelsRotation = 15,
                SubseparatorsCount = 1,
                SeparatorsPaint = new SolidColorPaint
                {
                    Color = s_gray,
                    StrokeThickness = 1,
                    PathEffect = new DashEffect(new float[] { 3, 3 })
                },
                SubseparatorsPaint = new SolidColorPaint
                {
                    Color = s_gray2,
                    StrokeThickness = 0.5f
                },
                ZeroPaint = new SolidColorPaint
                {

                },
                TicksPaint = new SolidColorPaint
                {
                    Color = s_gray,
                    StrokeThickness = 1.5f
                },
                SubticksPaint = new SolidColorPaint
                {
                    Color = s_gray,
                    StrokeThickness = 1
                }
    }
