dev简单实现柱状图，曲线图

1、数据源代码:

 DataTable dt = new DataTable();
dt.Columns.Add("A");
            dt.Columns.Add("B", typeof(Int32));
            for (int i = 0; i < 10; i++)
            {
                if (i % 2 == 0)
                {
                    dt.Rows.Add("测试数据00" + i, 20 * i);
                }
                else
                {
                    dt.Rows.Add("测试数据00" + i, 5 * i);
                }
            }

2、图表主要代码:

        //根据选择显示不同的Char
        private void ShowChar(int index)
        {

            Series ss = null;
            switch (index)
            {
                case 0:
                    ss = new Series("数值", ViewType.Bar);
                    break;
                case 1:
                    ss = new Series("数值", ViewType.Spline);
                    break;
            }
            if (ss != null)
            {
                this.chartControl1.Series.Clear();
                ss.DataSource = dt;
                ss.ArgumentDataMember = "A";
                ss.ValueDataMembers[0] = "B";
                this.chartControl1.Series.Add(ss);
            }
        }
