MSChart使用总结

  最近一段时间要用MSChart写几个报表，所以刚开始接触，写了几个报表之后对MSchart有了一点总结

1.属性

1.1 Series

                                     Char1.Legends["Legend" + i].LegendStyle = LegendStyle.Column;//按列显示
                        Char1.Legends["Legend" + i].Docking = Docking.Right;//显示在右上角；
                        Char1.Series[seriesName].BorderWidth = 3;
                        //节点大小为5
                        Char1.Series[seriesName].MarkerSize = 7;
                       Char1.Series[seriesName].IsVisibleInLegend = false;

 

1.2 ChartAreas

     

[csharp]  view plain copy

1. Chart1.ChartAreas[0].AxisX.Interval = 1;   //设置X轴坐标的间隔为1  
2.     Chart1.ChartAreas[0].AxisX.IntervalOffset = 1;  //设置X轴坐标偏移为1  
3.     Chart1.ChartAreas[0].AxisX.LabelStyle.IsStaggered = true;   //设置是否交错显示，比如数据多的时候分成两行来显示   

 

[csharp]  view plain copy

1. //在y轴上有交点  
2.                 Char1.ChartAreas["ChartAreasValue"].AxisX.IsMarginVisible = false;  
3.                 Char1.Titles.Add(string.Format("{0}年勘测设计产值完成情况", this.ddlSearchYear.SelectedValue));  
4.                 Char1.ChartAreas["ChartAreasValue"].AxisY.Title = "单位：万元";  

1.3 图表

[csharp]  view plain copy

1. ChartDataTableHelper TableHelper = new ChartDataTableHelper();  
2.            //显示合计  
3.            TableHelper.Initialize(Char1,false);  

2.绑定

2.1  

[csharp]  view plain copy

1. //一个柱子  
2.   
3.                   DataRow[] dtChartData = DsResult.Tables["DtDeptResult"].Select("1=1");  
4.   
5.                    string xValueMember = "DeptName";  
6.                    string yValueMembers = "AllMark";  
7.   
8.                    chartDeptMark.DataSource = dtChart.DefaultView;  
9.                     chartDeptMark.Series.Add("Series1");  
10.                     chartDeptMark.Series["Series1"].XValueMember = xValueMember;  
11.                     chartDeptMark.Series["Series1"].YValueMembers = yValueMembers;  
12.   
13.   
14.   
15. //一条数据中的多列对应多个Y值  
16.   
17. DataRow[] drResult = GetValueOfYear().Select("StatYear=100");  
18.   
19.   for (int i = 0; i < 12; i++)  
20.                 {  
21.                     if (startMonth > 12)  
22.                     {  
23.                         startMonth -= 12;  
24.                     }  
25.                     montharr[i] = startMonth;  
26.                     string columnName = "CVM" + startMonth;  
27.                     Char1.Series["Series0"].Points.AddXY(startMonth.ToString(), drResult[0][columnName]);  
28.                     //Char1.Series["Series0"].XValueMember = montharr;  
29.                     startMonth++;  
30.                 }  
31.   
32.   
33.   
34. //多行数据  
35.   
36.                for (int i = 0; i < dtResult.Columns.Count; i++)  
37.                 {  
38.                     string columnName = dtResult.Columns[i].ColumnName;  
39.                     string seriesName = "Series" + i;  
40.   
41.                      Char1.Series.Add(seriesName);  
42.                     Char1.Series[seriesName].Points.DataBindXY                   (dtResult.DefaultView, "BelongType", dtResult.DefaultView, columnName);  
43.   
44.                                      }  

 

2.2  分裂饼图

[csharp]  view plain copy

1. DataTable dtResult = GetResult();  
2.             Char1.Series.Add("serie0");  
3.             Char1.Series["serie0"].Points.DataBind(dtResult.DefaultView, "BelongType", "BelongTypeRatio", "LegendText=" + "BelongType");  
4.              
5.             Char1.Series["serie0"].ChartType = (SeriesChartType)Enum.Parse(typeof(SeriesChartType), "Pie", true);  
6.             Char1.Legends.Add("Legend0");  
7.             Char1.Series["serie0"].Label = "#LEGENDTEXT:#PERCENT{P}";  
8.             Char1.Series["serie0"]["PieLabelStyle"] = "Outside";  
9.              
10.             对否将值作为标签来显示  
11.             Char1.Series["serie0"].IsValueShownAsLabel = true;  
12.             //分裂图  
13.             foreach (DataPoint point in Char1.Series["serie0"].Points)  
14.             {  
15.                 point["Exploded"] = "true";  
16.             }  

 

3.事件

[csharp]  view plain copy

1. //对图中的图形添加单击事件，该例子是单击柱子后调用前台函数，跳转详细页面  
2.   
3.  chartDeptMark.Series["Series1"].MapAreaAttributes = "οnclick=\"javascript:return DeptMark('#VALX');\"";
