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：

代码

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

/// <summary>
/// 立体饼状图操作类
/// </summary>
public class PieChartHelper
{
/// <summary>
/// 饼状图初始化设置
/// </summary>
/// <param name="pieChart"></param>
public static void 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>
public static void 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>
public static void 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>
public static void SetPieChartControl_Texts(System.Drawing.PieChart.PieChartControl pieChart, string [] textArray)
{
pieChart.Texts = textArray;
}

/// <summary>

/// </summary>
/// <param name="pieChart"></param>
/// <param name="tipArray"></param>
public static void SetPieChartControl_ToolTips(System.Drawing.PieChart.PieChartControl pieChart, string [] tipArray)
{
pieChart.ToolTips = tipArray;
}
}
