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
|
1
|
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)
|
1
2
|
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
|
1
2
3
4
5
6
7
8
9
|
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, 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();
}
