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

Chart1.ChartAreas[0].AxisX.Interval = 1;   //设置X轴坐标的间隔为1    Chart1.ChartAreas[0].AxisX.IntervalOffset = 1;  //设置X轴坐标偏移为1    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

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

1.3 图表

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

2.绑定

2.1

//一个柱子                  DataRow[] dtChartData = DsResult.Tables["DtDeptResult"].Select("1=1");                   string xValueMember = "DeptName";                   string yValueMembers = "AllMark";                   chartDeptMark.DataSource = dtChart.DefaultView;                    chartDeptMark.Series.Add("Series1");                    chartDeptMark.Series["Series1"].XValueMember = xValueMember;                    chartDeptMark.Series["Series1"].YValueMembers = yValueMembers;//一条数据中的多列对应多个Y值DataRow[] drResult = GetValueOfYear().Select("StatYear=100");  for (int i = 0; i < 12; i++)                {                    if (startMonth > 12)                    {                        startMonth -= 12;                    }                    montharr[i] = startMonth;                    string columnName = "CVM" + startMonth;                    Char1.Series["Series0"].Points.AddXY(startMonth.ToString(), drResult[0][columnName]);                    //Char1.Series["Series0"].XValueMember = montharr;                    startMonth++;                }//多行数据               for (int i = 0; i < dtResult.Columns.Count; i++)                {                    string columnName = dtResult.Columns[i].ColumnName;                    string seriesName = "Series" + i;                     Char1.Series.Add(seriesName);                    Char1.Series[seriesName].Points.DataBindXY                   (dtResult.DefaultView, "BelongType", dtResult.DefaultView, columnName);                                     }

2.2 分裂饼图

 DataTable dtResult = GetResult();             Char1.Series.Add("serie0");             Char1.Series["serie0"].Points.DataBind(dtResult.DefaultView, "BelongType", "BelongTypeRatio", "LegendText=" + "BelongType");                         Char1.Series["serie0"].ChartType = (SeriesChartType)Enum.Parse(typeof(SeriesChartType), "Pie", true);             Char1.Legends.Add("Legend0");             Char1.Series["serie0"].Label = "#LEGENDTEXT:#PERCENT{P}";             Char1.Series["serie0"]["PieLabelStyle"] = "Outside";                         ////对否将值作为标签来显示             Char1.Series["serie0"].IsValueShownAsLabel = true;             //分裂图             foreach (DataPoint point in Char1.Series["serie0"].Points)             {                 point["Exploded"] = "true";             }

3.事件

//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 chartDeptMark.Series["Series1"].MapAreaAttributes = "onclick=\"javascript:return DeptMark('#VALX');\"";
