.Net Excel 导出图表Demo(柱状图，多标签页)

1 使用插件名称Epplus，多个Sheet页数据应用，Demo为柱状图（Epplus支持多种图表）

2 Epplus 的安装和引用

   新建一个工程文件或控制台应用程序 打开 Vs2017 Tools 的Nuget 包管理器，使用命令 install-package Epplus 

  

3 开始在创建的工程中编写代码，实现功能

  

4 具体实现流程代码如下：

using OfficeOpenXml.Drawing;
using OfficeOpenXml.Drawing.Chart;
using OfficeOpenXml.Style;
using System;
using System.Collections.Generic;
using System.Drawing;
using System.IO;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

            if (newFile.Exists)

                newFile = new FileInfo(@"d:	est.xlsx");
            }

            using (ExcelPackage package = new ExcelPackage(newFile))
