Hi Naveen,
You can generate custom multiline labels in order to achieve this look - for example:
NChart chart = nChartControl1.Charts[0];
NPointSeries bar = new NPointSeries();
bar.Values.Add(10);
bar.Values.Add(20);
bar.Values.Add(30);
chart.Series.Add(bar);
NOrdinalScaleConfigurator ordinalScale = new NOrdinalScaleConfigurator();
ordinalScale.AutoLabels = false;
ordinalScale.Labels.Add("1\r\n1");
ordinalScale.Labels.Add("1\r\n2");
ordinalScale.Labels.Add("1\r\n3");
chart.Axis(StandardAxis.PrimaryX).ScaleConfigurator = ordinalScale;
Hope this helps - let us know if you have any questions.
