Easy way for Chart Setup using Chart.SetChartDataRange method

Aspose.Cells now provides Chart.SetChartDataRange() method to set up chart easily. Using this method, you will now not need to add series and category axis data separately.

The following sample code explains the use Chart.SetChartDataRange() method to set up chart easily.

// For complete examples and data files, please go to https://github.com/aspose-cells/Aspose.Cells-for-.NET
// The path to the documents directory.
string dataDir = RunExamples.GetDataDir(System.Reflection.MethodBase.GetCurrentMethod().DeclaringType);

// Create new workbook
Workbook workbook = new Workbook(FileFormatType.Xlsx);

// Access first worksheet
Worksheet worksheet = workbook.Worksheets[0];

// Add data for chart

// Category Axis Values
worksheet.Cells["A2"].PutValue("C1");
worksheet.Cells["A3"].PutValue("C2");
worksheet.Cells["A4"].PutValue("C3");

// First vertical series
worksheet.Cells["B1"].PutValue("T1");
worksheet.Cells["B2"].PutValue(6);
worksheet.Cells["B3"].PutValue(3);
worksheet.Cells["B4"].PutValue(2);

// Second vertical series
worksheet.Cells["C1"].PutValue("T2");
worksheet.Cells["C2"].PutValue(7);
worksheet.Cells["C3"].PutValue(2);
worksheet.Cells["C4"].PutValue(5);

// Third vertical series
worksheet.Cells["D1"].PutValue("T3");
worksheet.Cells["D2"].PutValue(8);
worksheet.Cells["D3"].PutValue(4);
worksheet.Cells["D4"].PutValue(2);

// Create Column chart with easy way
int idx = worksheet.Charts.Add(ChartType.Column, 6, 5, 20, 13);
Chart ch = worksheet.Charts[idx];
ch.SetChartDataRange("A1:D4", true);

// Save the workbook
workbook.Save(dataDir + "output_out.xlsx", SaveFormat.Xlsx);
