chartControl ViewType.Bar 用法测试

 使用方法 一、

Datatable ：

 chartControl1.Series.Clear();
            DataTable dt = new DataTable();
            dt.Columns.Add("X轴",Type.GetType("System.String"));
            dt.Columns.Add("线①", Type.GetType("System.Int32"));
            dt.Columns.Add("线②", Type.GetType("System.Int32"));
            dt.Columns.Add("线③", Type.GetType("System.Int32"));
            dt.Columns.Add("线④", Type.GetType("System.Int32"));

            for (int i = 0; i < 10;i++ )
            {
                Random rd = new Random ();
                DataRow dr = dt.NewRow();
                dr["X轴"] = ("类别"+i.ToString()) ;
                dr["线①"] = rd.Next(i*10,(i+1)*10); ;
                dr["线②"] = rd.Next(i * 10, (i + 1) * 10);
                dr["线③"] = rd.Next(i * 10, (i + 1) * 10);
                dr["线④"] = rd.Next(i * 10, (i + 1) * 10);
                dt.Rows.Add(dr);
            }
             
            for (int i = 1; i < dt.Columns.Count;i++ )
            {
                // 柱状图里的第二柱 
                //第一个参数 设置四个竖条的标注
                Series Series2 = new Series(dt.Columns[i].ColumnName, ViewType.Bar);
                Series2.DataSource = dt;
                Series2.ArgumentScaleType = ScaleType.Qualitative;

                Series2.ArgumentDataMember = "X轴"; //设置公共的X轴值（刻度）
                Series2.ValueScaleType = ScaleType.Numerical;
                //设置 单个Series2 Y轴的（值）
                Series2.ValueDataMembers.AddRange(new string[] { dt.Columns[i].ColumnName });
                chartControl1.Series.Add(Series2);                 
            }

 使用方法二、

代码如下：

Series series1 = new Series("测试", ViewType.Bar);
            series1.Points.Add(new SeriesPoint("A", 5));
            series1.Points.Add(new SeriesPoint("B", 8));
            series1.Points.Add(new SeriesPoint("C", 2));
            series1.Points.Add(new SeriesPoint("D", 17));

            this.chartControl1.Series.Add(series1);
