         Worksheet worksheet = workbook.getWorksheets().get(sheetIndex);
         worksheet.getCells().get("A1").putValue(50);
         worksheet.getCells().get("A2").putValue(100);
         worksheet.getCells().get("A3").putValue(150);

         worksheet.getCells().get("B1").putValue(60);
         worksheet.getCells().get("B2").putValue(32);
         worksheet.getCells().get("B3").putValue(50);
         worksheet.getCells().get("B4").putValue(40);
 
         //Adding a chart to the worksheet
         int chartIndex = workbook.getWorksheets().get(0).getCharts().add(ChartType.COLUMN, 3, 3, 15, 10);
         Chart chart = workbook.getWorksheets().get(0).getCharts().get(chartIndex);
         chart.getNSeries().add("A1:a3", true);
         chart.getNSeries().get(0).getTrendLines().add(TrendlineType.LINEAR, "MyTrendLine");
         Trendline line = chart.getNSeries().get(0).getTrendLines().get(0);
