Epplus 匯出圖表的 三個步驟
建立圖表、選擇資料、設定圖表樣式
3.1 建立圖表
3.2 選擇資料。 這是很關鍵的一步，設定Y軸資料區、X軸資料區
3.3 設定圖表樣式
匯出結果：

Epplus的圖表實現是很簡單的，它支援的圖表型別也很多，基本上能滿足我們的需求。建立圖表分為三步（以柱狀圖舉例）：
1、建立圖表
| 1 |
ExcelChart chart = worksheet.Drawings.AddChart("chart", eChartType.ColumnClustered);//eChartType中可以選擇圖表型別
|
2、選擇資料
這一步是很關鍵的一步，chart.Series.Add()方法所需引數為：chart.Series.Add(Y軸資料區,X軸資料區)
| 1 2 |
ExcelChartSerie serie = chart.Series.Add(worksheet.Cells[2, 3, 5, 3], worksheet.Cells[2, 1, 5, 1]);//設定圖表的x軸和y軸
serie.HeaderAddress = worksheet.Cells[1, 3];//設定圖表的圖例
|
3、設定圖表樣式
| 1 2 3 4 5 6 7 8 9 |
chart.SetPosition(150, 10);//設定位置
chart.SetSize(500, 300);//設定大小
chart.Title.Text ="銷量走勢";//設定圖表的標題
chart.Title.Font.Color = Color.FromArgb(89, 89, 89);//設定標題的顏色
chart.Title.Font.Size = 15;//標題的大小
chart.Title.Font.Bold =true;//標題的粗體
chart.Style = eChartStyle.Style15;//設定圖表的樣式
chart.Legend.Border.LineStyle = eLineStyle.Solid;
chart.Legend.Border.Fill.Color = Color.FromArgb(217, 217, 217);//設定圖例的樣式

基本上生成圖表就這麼些東西了，不過不同的圖表屬性可能略有差異，得根據具體圖表具體分析。
下面是例子的全部程式碼：
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的網格線
worksheet.Cells[1, 1].Value = "名稱";
worksheet.Cells[1, 2].Value = "價格";
worksheet.Cells[1, 3].Value = "銷量";
worksheet.Cells[2, 1].Value = "大米";
worksheet.Cells[2, 2].Value = 56;
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;
worksheet.Cells[5, 3].Value = 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 = "微軟雅黑";
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));

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]);

chart.SetSize(500, 300);
chart.Title.Text = "銷量走勢";
chart.Title.Font.Color = Color.FromArgb(89, 89, 89);
