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。

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 == 1)
{
ChangeEmployeeBarData();
}
else if (cmbType.SelectedIndex == 2)
{
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 = 0;
myDiagram.RotationAngleY = 0;
myDiagram.RotationAngleZ = 270;
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 > 0
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 = 0;
int delaysDay = 0;
int absencesDay = 0;
int ExceptionDay = 0;
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 == 2);
delaysDay += dsPaycodeList.Count(dspaycode => dspaycode.ID == employee.id && dspaycode.Paycode == 6);
absencesDay += dsPaycodeList.Count(dspaycode => dspaycode.ID == employee.id && dspaycode.Paycode == 8);
ExceptionDay += dsPaycodeList.Count(dspaycode => dspaycode.ID == employee.id && dspaycode.Paycode == 11) +
dsPaycodeList.Count(dspaycode => dspaycode.ID == employee.id && dspaycode.Paycode == 12);
}
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。
