            float y = item.Appearance.Position.Y;

            item.Appearance.Position.Auto = false;

            item.Appearance.Position.Y = y;
            item.Appearance.Position.X = x + 620;
            //item.Appearance.Position.X = x + (float)(maxVal);
        }
    }
}

 

 

This is the small piece of code trying to get the label on right side.

Code value everything is correct but final output is not coming up with what I expected.

List<string> lLabel = new List<string>();

        foreach (DataRow dr in ds.Tables[0].Rows)
        {
            if (!lLabel.Contains(dr["ResourceName"].ToString()))
                lLabel.Add(dr["ResourceName"].ToString());
        }

        RadChart1.PlotArea.XAxis.MaxItemsCount = 0;

        RadChart1.PlotArea.XAxis.AddRange(1, lLabel.Count, 1);

        for (int i = 0; i < lLabel.Count; i++)
        {
            RadChart1.PlotArea.XAxis[i].TextBlock.Text = lLabel[i];
        }

See attached chart image files I would like to combine the both  means

Chart1.png one plotting is correct .

Chart2.png right side name is coming up correctly but chart is not correct like chart1.png.

I want chart1 chart  with lable like chart2.

please help how to fix this issue

Hello Dhamodharan,

Based on the supplied information, it is hard to determine what is causing this unwanted behavior. If the problem persists, you can 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.
