Hi,
The following code shows how to create a cluster bar with custom x category labels:
NChart chart = nChartControl1.Charts[0];
NBarSeries bar1 = new NBarSeries();
bar1.Values.Add(10);
bar1.Values.Add(20);
bar1.Values.Add(30);
chart.Series.Add(bar1);
NBarSeries bar2 = new NBarSeries();
bar2.MultiBarMode = MultiBarMode.Clustered;
bar2.Values.Add(30);
bar2.Values.Add(30);
bar2.Values.Add(40);
chart.Series.Add(bar2);
NOrdinalScaleConfigurator scaleX = chart.Axis(StandardAxis.PrimaryX).ScaleConfigurator as NOrdinalScaleConfigurator;
scaleX.AutoLabels = false;
scaleX.Labels.Add("Car");
scaleX.Labels.Add("Bus");
scaleX.Labels.Add("Plane");
Hope this helps - let us know if you meet any problems.
