Hi
I want to set the position of label in the middle of the line. I have attached image of my chart where label name "label 2" is at the top of line, How can I set the position of that label in middle of the line.
 

Hi
Thank you for reply,
but I don't understand after finding center point of line, how to set that point in label for change the position of label.

Hi Shweta,

You can use a point series in XY scatter mode for this purpose:

   NCartesianChart chart = (NCartesianChart)nChartControl1.Charts[0];

    NPointSeries point = new NPointSeries();
    point.Size = new NLength(0);
    chart.Series.Add(point);
    point.DataLabelStyle.Visible = true;
    point.DataLabelStyle.TextStyle.StringFormatStyle.HorzAlign = Nevron.HorzAlign.Center;
    point.DataLabelStyle.TextStyle.StringFormatStyle.VertAlign = Nevron.VertAlign.Center;
    point.DataLabelStyle.VertAlign = Nevron.VertAlign.Center;
    point.DataLabelStyle.Format = "<label>";
    point.UseXValues = true;
    point.Values.Add(10);
    point.XValues.Add(10);
    point.Labels.Add("Some Label");

This will display a centered label at [10,10] - you can also display labels using annotations - check out example All Examples \ Panels \ Annotations for more information... Let us know if you meet any problems.
