aspose.cells = require("aspose.cells");
var fs = require("fs");
var workbook = new aspose.cells.Workbook("sparkline.xlsx");
var sparkline = workbook.getWorksheets().get(0).getSparklineGroupCollection().get(0).getSparklineCollection().get(0);
var imgWriteStream = fs.createWriteStream("sparkline.jpeg");
var imgOptions = new aspose.cells.ImageOrPrintOptions();
imgOptions.setHorizontalResolution(200);
