C# Code:

chartControl1.Series.Clear();

// 柱状图里的第一个柱
Series Series1 = new Series("当年数据", ViewType.Bar);
Series1.DataSource = data;
Series1.ArgumentScaleType = ScaleType.Qualitative;

// 以哪个字段进行显示
Series1.ArgumentDataMember = "GROUPCOLUMNNAME";
Series1.ValueScaleType = ScaleType.Numerical;

// 柱状图里的柱的取值字段
Series1.ValueDataMembers.AddRange(new string[] { "CURRENTQUANTITY" });

// 柱状图里的第二柱
Series Series2 = new Series("累计数据", ViewType.Bar);
Series2.DataSource = data;
Series2.ArgumentScaleType = ScaleType.Qualitative;
Series2.ArgumentDataMember = "GROUPCOLUMNNAME";
Series2.ValueScaleType = ScaleType.Numerical;
Series2.ValueDataMembers.AddRange(new string[] { "TOTALQUANTITY" });
chartControl1.Series.Add(Series1);
chartControl1.Series.Add(Series2);
