MSChart绘图控件中折线图和柱形图画法

首先在前台拖入一个名为chart1的MSChart控件

   　　　　　
//折线图
　　　　　　　string strLegend = "Legend1";
            Legend lg = new Legend(strLegend);
            lg.IsDockedInsideChartArea = false;
            lg.TitleAlignment = System.Drawing. StringAlignment.Center;
            chart1.Legends.Add(lg);
 
            ChartArea ca = new ChartArea();
            ca.AxisX.MajorGrid.Enabled = false;
            ca.AxisX.MajorTickMark.Enabled = false;
            ca.AxisY.MajorGrid.LineDashStyle = ChartDashStyle.NotSet;
            int index = ;
            Series MyScore = new Series( "我的得分" );
            MyScore.ChartType = SeriesChartType.Line;
            MyScore.Legend = "Legend1";
            MyScore.ChartArea = "ChartArea1";
            MyScore.BorderWidth = ;
            Series HighScore = new Series( "最高分" );
            HighScore.ChartType = SeriesChartType.Line;
            HighScore.Legend = "Legend1";
            HighScore.ChartArea = "ChartArea1";
            MyScore.BorderWidth = ;
            Series AvgScore = new Series( "平均分" );
            AvgScore.ChartType = SeriesChartType.Line;
            AvgScore.Legend = "Legend1";
            AvgScore.ChartArea = "ChartArea1";
            MyScore.BorderWidth = ;
            foreach (DataRow dr in m_table.Rows)
            {
                DataPoint dp;
                if (dr["MyScore" ] == null)
                    continue;
                dp = new DataPoint (index, Convert.ToDouble(dr["MyScore" ]));
                dp.AxisLabel = dr[ "Name"].ToString();
                dp.Label = Convert.ToInt32(dr["MyScore" ]).ToString();
                dp.BorderWidth = ;
                dp.MarkerStyle = System.Windows.Forms.DataVisualization.Charting.MarkerStyle .Star10;
                MyScore.Points.Add(dp);
                dp = new DataPoint (index, Convert.ToDouble(dr["HighScore" ]));
                dp.AxisLabel = dr[ "Name"].ToString();
                dp.Label = Convert.ToInt32(dr["HighScore" ]).ToString();
                dp.BorderWidth = ;
                dp.MarkerStyle = System.Windows.Forms.DataVisualization.Charting.MarkerStyle .Star10;
                HighScore.Points.Add(dp);
                dp = new DataPoint (index, Convert.ToDouble(dr["AvgScore" ]));
                dp.AxisLabel = dr[ "Name"].ToString();
                dp.Label = Convert.ToInt32(dr["AvgScore" ]).ToString();
                dp.BorderWidth = ;
                dp.MarkerStyle = System.Windows.Forms.DataVisualization.Charting.MarkerStyle .Star10;
                AvgScore.Points.Add(dp);
                index++;
            }
            chart1.Series.Add(MyScore);
            chart1.Series.Add(HighScore);
            chart1.Series.Add(AvgScore);
            chart1.ChartAreas.Add(ca);

　　　　　　　　　
//柱形图
　　　　　　　　　 string strLegend = "Legend1" ;
                Legend lg = new Legend(strLegend);
                lg.IsDockedInsideChartArea = false;
                lg.TitleAlignment = System.Drawing.StringAlignment .Center;
                chart1.Legends.Add(lg);
 
                ChartArea ca = new ChartArea();
                ca.AxisX.MajorGrid.Enabled = false;
                ca.AxisX.MajorTickMark.Enabled = false;
                ca.AxisY.MajorGrid.LineDashStyle = ChartDashStyle.NotSet;
                int index = ;
                foreach (DataRow dr in dt.Rows)
                {
                    Series s = new Series(dr["CourseTermName" ].ToString());
                    s.ChartType = SeriesChartType.Column;
                    s.Legend = "Legend1";
                    s.ChartArea = "ChartArea1";
                    DataPoint dp;
                    dp = new DataPoint (index, Convert.ToDouble(dr["Score" ]));
                    dp.AxisLabel = dr[ "CourseTermName"].ToString();
                    dp.Label = Convert.ToInt32(dr["Score" ]).ToString();
                    dp.MarkerStyle = System.Windows.Forms.DataVisualization.Charting.MarkerStyle .Star10;
                    s.Points.Add(dp);
                    chart1.Series.Add(s);
                    index++;
                }
                chart1.ChartAreas.Add(ca);

设置序列的BorderWidth可以改变线条的粗细，它是一个int值，值越大，线条越粗；

设置序列的MarkerStyle可以 显示出数据点标记，它是一个枚举，有多个样式，圆点、三角、矩形什么的，甚至可以通过MarkerImage来指定一个图形作为数据点，属性方面可以通过 MarkerSize和MarkerBorderWidth来指定数据点大小，MarkerColor和MarkerBorderColor来指定数据点 颜色。

希望对大家有帮助。以上都是我在项目中实现过的。
