Epplus的图表实现是很简单的，它支持的图表类型也很多，基本上能满足我们的需求。创建图表分为三步（以柱状图举例）：

1、创建图表

ExcelChart chart = worksheet.Drawings.AddChart("chart", eChartType.ColumnClustered);//eChartType中可以选择图表类型

2、选择数据

    这一步是很关键的一步，chart.Series.Add()方法所需参数为：chart.Series.Add(Y轴数据区,X轴数据区) 

ExcelChartSerie serie = chart.Series.Add(worksheet.Cells[2, 3, 5, 3], worksheet.Cells[2, 1, 5, 1]);//设置图表的x轴和y轴
serie.HeaderAddress = worksheet.Cells[1, 3];//设置图表的图例

3、设置图表样式   

chart.SetPosition(150, 10);//设置位置
chart.SetSize(500, 300);//设置大小
chart.Title.Text = "销量走势";//设置图表的标题
chart.Title.Font.Color = Color.FromArgb(89, 89, 89);//设置标题的颜色
chart.Title.Font.Size = 15;//标题的大小
chart.Title.Font.Bold = true;//标题的粗体
chart.Style = eChartStyle.Style15;//设置图表的样式
chart.Legend.Border.LineStyle = eLineStyle.Solid;
chart.Legend.Border.Fill.Color = Color.FromArgb(217, 217, 217);//设置图例的样式

 基本上生成图表就这么些东西了，不过不同的图表属性可能略有差异，得根据具体图表具体分析。

 下面是例子的全部代码：

 FileInfo newFile = new FileInfo(@"d:\test.xlsx");
            if (newFile.Exists)
            {
                newFile.Delete();
                newFile = new FileInfo(@"d:\test.xlsx");
            }
            using (ExcelPackage package = new ExcelPackage(newFile))
            {
                ExcelWorksheet worksheet = package.Workbook.Worksheets.Add("test");

                worksheet.Cells.Style.WrapText = true;
                worksheet.View.ShowGridLines = false;//去掉sheet的网格线

                worksheet.Cells[1, 1].Value = "名称";
                worksheet.Cells[1, 2].Value = "价格";
                worksheet.Cells[1, 3].Value = "销量";

                worksheet.Cells[2, 3].Value = 100;

                worksheet.Cells[3, 1].Value = "玉米";
                worksheet.Cells[3, 2].Value = 45;
                worksheet.Cells[3, 3].Value = 150;

                worksheet.Cells[4, 1].Value = "小米";
                worksheet.Cells[4, 2].Value = 38;
                worksheet.Cells[4, 3].Value = 130;

                worksheet.Cells[5, 1].Value = "糯米";
                worksheet.Cells[5, 2].Value = 22;

                }

                using (ExcelRange range = worksheet.Cells[1, 1, 1, 3])
                {
                    range.Style.Font.Bold = true;
                    range.Style.Font.Color.SetColor(Color.White);
                    range.Style.Font.Name = "微软雅黑";

                    range.Style.Fill.BackgroundColor.SetColor(Color.FromArgb(128, 128, 128));
                }
