WinForm"立体饼状图实现(附源码示例)" 之配餐系统的开发

       本文所要将的是在“配餐系统”开发中 立体饼状图效果的实现，直接贴出代码和附上示例，相信需要的朋友可以很容易使用！项目中的效果图，如下：

  实现 应用的是 System.Drawing.PieChart.PieChartControl 控件, PieChartHelper类如下：

using System;
using System.Collections;
using System.Drawing;
using System.Text;

///<summary>
/// 立体饼状图操作类
///</summary>
publicclass PieChartHelper
{
    ///<summary>
    /// 饼状图初始化设置
    ///</summary>
    ///<param name="pieChart"></param>
publicstaticvoid Init_PieChart(System.Drawing.PieChart.PieChartControl pieChart)
    {
        pieChart.EdgeColorType = System.Drawing.PieChart.EdgeColorType.Contrast;
        pieChart.EdgeLineWidth =1;//设置饼块的边框线的宽度
        //饼状图(上下左右)距离边框(PieChart控件的边框)都为5
        pieChart.LeftMargin = 5f;
        pieChart.RightMargin = 5f;
        pieChart.TopMargin = 5f;
        pieChart.BottomMargin = 5f;
        pieChart.FitChart =true;
        pieChart.SliceRelativeHeight =0.15f;//设置饼块的厚(高)度
        pieChart.InitialAngle =30;
        pieChart.ShadowStyle = System.Drawing.PieChart.ShadowStyle.GradualShadow;
        pieChart.BackColor = System.Drawing.Color.Transparent;
    }

    ///<summary>
    /// 设置饼状图各项对应的值
    ///</summary>
    ///<param name="pieChart"></param>
    ///<param name="valArray"></param>
publicstaticvoid SetPieChartControl_Values(System.Drawing.PieChart.PieChartControl pieChart, decimal[] valArray)
    {
        pieChart.Values = valArray;
    }

    ///<summary>
    /// 设置饼状图各项对应的颜色
    ///</summary>
    ///<param name="pieChart"></param>
    ///<param name="colArray"></param>
publicstaticvoid SetPieChartControl_Colors(System.Drawing.PieChart.PieChartControl pieChart, Color[] colArray)
    {
        ArrayList colors =new ArrayList();
        foreach (Color col in colArray)
        {
            colors.Add(Color.FromArgb(125, col));
        }
        pieChart.Colors = (Color[])colors.ToArray(typeof(Color)); ;
    }

    ///<summary>
    /// 设置饼状图各项对应的文本
    ///</summary>
    ///<param name="pieChart"></param>
    ///<param name="textArray"></param>
publicstaticvoid SetPieChartControl_Texts(System.Drawing.PieChart.PieChartControl pieChart, string[] textArray)
    {
        pieChart.Texts = textArray;
    }

    ///<summary>
    /// 设置饼状图各项对应的文本提示
    ///</summary>
    ///<param name="pieChart"></param>
    ///<param name="tipArray"></param>
publicstaticvoid SetPieChartControl_ToolTips(System.Drawing.PieChart.PieChartControl pieChart, string[] tipArray)
    {
        pieChart.ToolTips = tipArray;
    }
}
