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 = http://www.mamicode.com/"名称"; worksheet.Cells[1, 2].Value = http://www.mamicode.com/"价格"; worksheet.Cells[1, 3].Value = http://www.mamicode.com/"销量"; worksheet.Cells[2, 1].Value = http://www.mamicode.com/"大米"; worksheet.Cells[2, 2].Value = http://www.mamicode.com/56; worksheet.Cells[2, 3].Value = http://www.mamicode.com/100; worksheet.Cells[3, 1].Value = http://www.mamicode.com/"玉米"; worksheet.Cells[3, 2].Value = http://www.mamicode.com/45; worksheet.Cells[3, 3].Value = http://www.mamicode.com/150; worksheet.Cells[4, 1].Value = http://www.mamicode.com/"小米"; worksheet.Cells[4, 2].Value = http://www.mamicode.com/38; worksheet.Cells[4, 3].Value = http://www.mamicode.com/130; worksheet.Cells[5, 1].Value = http://www.mamicode.com/"糯米"; worksheet.Cells[5, 2].Value = http://www.mamicode.com/22; worksheet.Cells[5, 3].Value = http://www.mamicode.com/200; using (ExcelRange range = worksheet.Cells[1, 1, 5, 3]) { range.Style.HorizontalAlignment = ExcelHorizontalAlignment.Center; range.Style.VerticalAlignment = ExcelVerticalAlignment.Center; } 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.Font.Size = 12; range.Style.Fill.PatternType = ExcelFillStyle.Solid; range.Style.Fill.BackgroundColor.SetColor(Color.FromArgb(128, 128, 128)); } worksheet.Cells[1, 1].Style.Border.BorderAround(ExcelBorderStyle.Thin, Color.FromArgb(191, 191, 191)); worksheet.Cells[1, 2].Style.Border.BorderAround(ExcelBorderStyle.Thin, Color.FromArgb(191, 191, 191)); worksheet.Cells[1, 3].Style.Border.BorderAround(ExcelBorderStyle.Thin, Color.FromArgb(191, 191, 191)); worksheet.Cells[2, 1].Style.Border.BorderAround(ExcelBorderStyle.Thin, Color.FromArgb(191, 191, 191)); worksheet.Cells[2, 2].Style.Border.BorderAround(ExcelBorderStyle.Thin, Color.FromArgb(191, 191, 191)); worksheet.Cells[2, 3].Style.Border.BorderAround(ExcelBorderStyle.Thin, Color.FromArgb(191, 191, 191)); worksheet.Cells[3, 1].Style.Border.BorderAround(ExcelBorderStyle.Thin, Color.FromArgb(191, 191, 191)); worksheet.Cells[3, 2].Style.Border.BorderAround(ExcelBorderStyle.Thin, Color.FromArgb(191, 191, 191)); worksheet.Cells[3, 3].Style.Border.BorderAround(ExcelBorderStyle.Thin, Color.FromArgb(191, 191, 191)); worksheet.Cells[4, 1].Style.Border.BorderAround(ExcelBorderStyle.Thin, Color.FromArgb(191, 191, 191)); worksheet.Cells[4, 2].Style.Border.BorderAround(ExcelBorderStyle.Thin, Color.FromArgb(191, 191, 191)); worksheet.Cells[4, 3].Style.Border.BorderAround(ExcelBorderStyle.Thin, Color.FromArgb(191, 191, 191)); worksheet.Cells[5, 1].Style.Border.BorderAround(ExcelBorderStyle.Thin, Color.FromArgb(191, 191, 191)); worksheet.Cells[5, 2].Style.Border.BorderAround(ExcelBorderStyle.Thin, Color.FromArgb(191, 191, 191)); worksheet.Cells[5, 3].Style.Border.BorderAround(ExcelBorderStyle.Thin, Color.FromArgb(191, 191, 191)); ExcelChart chart = worksheet.Drawings.AddChart("chart", eChartType.ColumnClustered); ExcelChartSerie serie = chart.Series.Add(worksheet.Cells[2, 3, 5, 3], worksheet.Cells[2, 1, 5, 1]); serie.HeaderAddress = worksheet.Cells[1, 3]; chart.SetPosition(150, 10); chart.SetSize(500, 300); chart.Title.Text = "销量走势"; chart.Title.Font.Color = Color.FromArgb(89, 89, 89); chart.Title.Font.Size = 15; chart.Title.Font.Bold = true; chart.Style = eChartStyle.Style15; chart.Legend.Border.LineStyle = eLineStyle.Solid; chart.Legend.Border.Fill.Color = Color.FromArgb(217, 217, 217); package.Save(); }
