EPPlus graph in separate sheet

问题:

How do I create a graph as a separate worksheet rather than as a drawing in an existing worksheet using EPPLus?

回答1:

In version 4.0.4.0 (download the code from codeplex, for correct a bug in saving file), you can use:

workbook.Worksheets.AddChart(name, type); 

this will create a sheet with only the chart.

回答2:

You should do what you want. That is the chart you want to plot, plot it in the sheet you want.

ExcelPackage pck = new ExcelPackage(); ExcelRange r1, r2;  var sheet1 = pck.Workbook.Worksheets.Add("data_sheet"); var sheet2 = pck.Workbook.Worksheets.Add("chart_sheet"); var chart = (OfficeOpenXml.Drawing.Chart.ExcelBarChart)sheet2.Drawings.AddChart("some_name", OfficeOpenXml.Drawing.Chart.eChartType.ColumnClustered); chart.Legend.Position = OfficeOpenXml.Drawing.Chart.eLegendPosition.Right; chart.Legend.Add(); chart.SetPosition(1, 0, 1, 0); chart.SetSize(600, 400); chart.DataLabel.ShowValue = true;  r1 = sheet1.Cells["A3:A10"]; r2 = sheet1.Cells["B3:B10"]; chart.Series.Add(r2, r1);  chart.Style = OfficeOpenXml.Drawing.Chart.eChartStyle.Style21; chart.Title.Text = "Some title"; chart.XAxis.Title.Text = "X axis name"; chart.YAxis.Title.Text = "Y axis name"; 

In this example, chart is plotted in sheet2 but data is in sheet1. Hope this is helpful.
