    Hello Abdulhameed,

    Basically, when the axis is autoranged, the values are arranged for best layout and visibility. Thus, if you have a larger number of values, not all of them will be rendered along the axis. One possible approach in this case would be to turn off the autorange for the axis, set the min and max values, as well as the step. This may look something like this:

    RadChart1.DefaultView.ChartArea.AxisX.AutoRange = false;
    RadChart1.DefaultView.ChartArea.AxisX.Step = 1;
    RadChart1.DefaultView.ChartArea.AxisX.MinValue = 0;
    RadChart1.DefaultView.ChartArea.AxisX.MaxValue = 37;

    Additionally, such a setup is only meaningful, when the axis is numeric - i.e. you are setting xvalues along it. If you use an xCategory, all values will be rendered:

    ItemMapping itemMapping1 = new ItemMapping();
    itemMapping1.FieldName = "index";
    itemMapping1.DataPointMember = DataPointMember.XCategory;

    thus, in your case, you can use an xcategory for the month values, and all of them should be rendered.
    I hope this information helps.
