Hi Naveen,
We could not find the attachment, but most likely you want to insert categorical labels - for example:
NOrdinalScaleConfigurator scaleX = chart.Axis(StandardAxis.PrimaryX).ScaleConfigurator as NOrdinalScaleConfigurator;
scaleX.AutoLabels = false;
scaleX.Labels.Add("One");
scaleX.Labels.Add("Two");
scaleX.Labels.Add("Three");
