Incorrect behavior of the line at the beginning and at the end at identical values

Hello ,

Thank you for writing.  

Since RadChart is obsolete, I would recommend you to use RadChartView which renders the equal values in an AreaSeries as in the attached screenshot.

public Form1()
{
    InitializeComponent();

    AreaSeries areaSeries = new AreaSeries();
    for (int i = 0; i < 5; i++)
    {
        areaSeries.DataPoints.Add(new CategoricalDataPoint(10, i));
    }

    this.radChartView1.Series.Add(areaSeries);
}

I hope this information helps. Should you have further questions I would be glad to help.

Regards,
Dess
