    Hello,

    I search the way to have a good X axis for a month graph.
    I have 1 point by day, all points at midnight.

    To create the Axis I do :
    xAxis.AutoRange = false;
    xAxis.IsDateTime = true;
    //xAxis.Step = firstDayOfMonth.AddDays(1).ToOADate() - firstDayOfMonth.ToOADate(); -> this line RETURN 1
    xAxis.AddRange(firstDayOfMonth.ToOADate(), lastDayOfMonth().ToOADate(), 1);
    xAxis.DefaultLabelFormat = "dd";   // Just Day number

    I have 2 problems :
    - When I zoom, the same date number appear several time in my axis
    - When I move the horizontal zoom scroll bar, my points are not aligned any more
    I attach an image to this post to show it to you

    Can you help me please ?
    Thank you in advance

    Hello JC,

    Based on the supplied information, it is hard to determine what is causing this unwanted behavior. To further trace the problem, it will be best if you open a formal support ticket, and send us a small working project, demonstrating your setup, and showing the unwanted behavior. We will debug it locally, and advise you further.

    So,

    To resolve this problem I had to disabled zooming, create a X mapping on Date.Day, set do :

    xAxis.AutoRange = false;
    xAxis.IsDateTime = false;
    xAxis.AddRange(1, DateTime.DaysInMonth(myYear, myMonth), 1);
    _chart.DefaultView.ChartArea.AxisX.DefaultLabelFormat = string.Empty;

    I Have not found better.
    Thank you anyway for your reply
