Bar 3D 和Pie 3D的统计图形

最近在做一个关于图形统计的界面，主要用到的是Dev控件ChartControl（功能很强大，能解决基本和复杂图形统计问题）。

ChartControl主要有Diagram、Series、Legend三个重要属性

diagram主要是用来控制图形X、Y、Z轴显示的样式和是否允许旋转以及旋转的角度和绕那个轴旋转。

series主要是用来给chartcontrol控件增加各种图形，图形的种类用viewtype来控制。

legend主要是用来说明图形的分类（可以说是图例）。

第一部分是以饼状图来分类显示各种情况所占的百分比：例如最近一段时间水果占销售总量的百分比是多少等等。

代码主要是先实例化chartcontrol，再对chartcontrol进行属性赋值最后进行绑定数据，代码如下：

 ChartControl staticsChart = new ChartControl();//create the chart control
        Series series1 = null;
        Series series2 = null;
        Series series3 = null;
        Series series4 = null;
/// <summary>
        /// config the format for doughnut3D
        /// </summary>
        private void AddDoughnut3D()
        {
            series1= new Series("Doughnut Sereis 1", ViewType.Doughnut3D);//add series1
            ChangeTheDouguntData();
            staticsChart.Series.Add(series1);
            series1.Label.TextPattern = "{A}{VP:0%}";
            ((Doughnut3DSeriesView)series1.View).HoleRadiusPercent=;
            //((Doughnut3DSeriesView)series1.View).ExplodedPoints.Add(series1.Points[0]);export diagram
            ((SimpleDiagram3D)staticsChart.Diagram).RotationType = RotationType.UseAngles;
            ((SimpleDiagram3D)staticsChart.Diagram).RotationAngleX = -;
            SetChartFormat();
        }
  private void SetChartFormat()
        {
            staticsChart.CrosshairOptions.ShowArgumentLabels = true;
            staticsChart.CrosshairOptions.ShowArgumentLine = true;
            staticsChart.CrosshairOptions.ShowCrosshairLabels = true;
            staticsChart.BackColor = Color.Transparent;
            staticsChart.PaletteBaseColorNumber = ;
            staticsChart.PaletteName = "Green";
            staticsChart.Titles.Clear();
            ChartTitle chartTitle1 = new ChartTitle();
            staticsChart.Text = "Data Graphics";
            staticsChart.Titles.Add(chartTitle1);
            staticsChart.Legend.UseCheckBoxes = false;
            staticsChart.Legend.Direction = LegendDirection.LeftToRight;
            staticsChart.Legend.AlignmentHorizontal = LegendAlignmentHorizontal.Center;
            staticsChart.Dock = DockStyle.Fill;
            this.pnlAddDiagram.Controls.Add(staticsChart);
        }
 private void ChangeTheDouguntData()
        {
            DataTable diagramData = GetAllEmployeeDaySummary();
            int attendanceNumber = ;
            int delaysNumber = ;
            int absencesNumber = ;
            int exceptionNumber = ;
            if (diagramData.Rows.Count > )
            {
                attendanceNumber = diagramData.Select("pc_code=2" + " and pc_results>0").Length;
                delaysNumber = diagramData.Select("pc_code=6" + " and pc_results>0").Length;
                absencesNumber = diagramData.Select("pc_code=8" + " and pc_results>0").Length;
                exceptionNumber = diagramData.Select("pc_code in(11,12) " + " and pc_results>0").Length;
            }
            series1.Points.AddRange(new SeriesPoint[]{
            new SeriesPoint("Attendance",attendanceNumber),
            new SeriesPoint("Delays",delaysNumber),
            new SeriesPoint("Absences",absencesNumber),
            new SeriesPoint("Exception",exceptionNumber)});
        }

第二部分是柱状图，思路和饼状图差不多，series设置的不一样。

实现代码：

  private void AddBar3DChart()
         {
             series1 = new Series("Attendance", ViewType.Bar3D);
             series2 = new Series("Delays", ViewType.Bar3D);
             series3 = new Series("Absences", ViewType.Bar3D);
             series4 = new Series("Exception", ViewType.Bar3D);
             if (cmbType.SelectedIndex == )
             {
                 ChangeEmployeeBarData();
             }
             else if (cmbType.SelectedIndex == )
             {
                 ChangeDepartmentBarData();
             }
             staticsChart.Series.AddRange(new Series[] { series1, series2, series3, series4 });
             //series1.Label.ResolveOverlappingMode = ResolveOverlappingMode.Default;

             #region set the series view's value
             Bar3DSeriesView myView1 = (Bar3DSeriesView)series1.View;
             myView1.BarDepthAuto = false;
             myView1.BarDepth = 0.2;
             myView1.BarWidth = 0.5;
             Bar3DSeriesView myView2 = (Bar3DSeriesView)series2.View;

             myView2.BarDepthAuto = false;
             myView2.BarDepth = 0.2;
             myView2.BarWidth = 0.5;
             Bar3DSeriesView myView3 = (Bar3DSeriesView)series3.View;
             myView3.BarDepthAuto = false;
             myView3.BarDepth = 0.2;
             myView3.BarWidth = 0.5;
             Bar3DSeriesView myView4 = (Bar3DSeriesView)series4.View;
             myView4.BarDepthAuto = false;
             myView4.BarDepth = 0.2;
             myView4.BarWidth = 0.5;
             #endregion

             XYDiagram3D myDiagram = (XYDiagram3D)staticsChart.Diagram;
             myDiagram.RotationType = RotationType.UseAngles;
             myDiagram.RotationOrder = RotationOrder.XYZ;
             myDiagram.RotationAngleX = ;
             myDiagram.RotationAngleY = ;
             myDiagram.RotationAngleZ = ;
             myDiagram.RuntimeScrolling = true;
             SetChartFormat();
         }

 private void ChangeDepartmentBarData()
         {
             List<Employee> empList = treeModule.CheckedEmps;
             List<Department> depList = treeModule.CheckedDepartment;
             DateTime fromDate = dteFromDate.DateTime;
             DateTime endDate = dteEndDate.DateTime;
             List<DaySummary> dsList = new DaySummaryBLL().GetEmployeesDailySummary(empList, fromDate, endDate);
             List<Paycode> paycodeList = new PaycodeBLL().GetMainFields();
             var dsPaycodeList = from ds in dsList
                                 join p in paycodeList on ds.paycode.id equals p.id
                                 where ds.pc_results >
                                 orderby ds.employee.id ascending, ds.att_date descending
                                 select new { ID = ds.employee.id, Minutes = ds.pc_results, Date = ds.att_date, Paycode = p.pc_code };
             foreach (Department dep in depList)
             {
                 int attendanceDay = ;
                 int delaysDay = ;
                 int absencesDay = ;
                 int ExceptionDay = ;
                 List<Employee> depEmpList = new EmployeeBLL().GetMainFields(string.Format("where e.department.id={0}", dep.id));
                 foreach (Employee employee in depEmpList)
                 {
                     attendanceDay += dsPaycodeList.Count(dspaycode => dspaycode.ID == employee.id && dspaycode.Paycode == );
                     delaysDay += dsPaycodeList.Count(dspaycode => dspaycode.ID == employee.id && dspaycode.Paycode == );
                     absencesDay += dsPaycodeList.Count(dspaycode => dspaycode.ID == employee.id && dspaycode.Paycode == );
                     ExceptionDay += dsPaycodeList.Count(dspaycode => dspaycode.ID == employee.id && dspaycode.Paycode == ) +
                         dsPaycodeList.Count(dspaycode => dspaycode.ID == employee.id && dspaycode.Paycode == );
                 }
                 series1.Points.Add(new SeriesPoint(dep.dept_name.ToString(), attendanceDay));
                 series2.Points.Add(new SeriesPoint(dep.dept_name.ToString(), delaysDay));
                 series3.Points.Add(new SeriesPoint(dep.dept_name.ToString(), absencesDay));
                 series4.Points.Add(new SeriesPoint(dep.dept_name.ToString(), ExceptionDay));
             }
         }

以上主要是提供一个思路怎么来解决这种图形统计类问题，以及怎么进行数据绑定，如有不对的地方请指出。
