Class Sparkline

java.lang.Object

com.aspose.cells.Sparkline

public class Sparkline
extends java.lang.Object

A sparkline represents a tiny chart or graphic in a worksheet cell that provides a visual representation of data.

Example

 
         Workbook book = new Workbook(); 
         Worksheet sheet = book.getWorksheets().get(0);
 
         sheet.getCells().get("A1").putValue(5);
         sheet.getCells().get("B1").putValue(2);
         sheet.getCells().get("C1").putValue(1);
         sheet.getCells().get("D1").putValue(3);
 
         // Define the CellArea
         CellArea ca = new CellArea();
         ca.StartColumn = 4;
         ca.EndColumn = 4;
         ca.StartRow = 0;
         ca.EndRow = 0;
 
         int idx = sheet.getSparklineGroups().add(com.aspose.cells.SparklineType.LINE, sheet.getName() + "!A1:D1", false, ca);
 
         SparklineGroup group = sheet.getSparklineGroups().get(idx);
         idx = group.getSparklines().add(sheet.getName() + "!A1:D1", 0, 4);
         Sparkline line = group.getSparklines().get(idx);
         System.out.println("Saprkline data range: " + line.getDataRange() + ", row: " + line.getRow() + ", column: " + line.getColumn());
         line.toImage("output.png", new ImageOrPrintOptions());
