    sheet.getRangeByName('A3').setDateTime(DateTime(2014, 02, 14, 14, 14, 14));
     sheet.getRangeByName('A3').numberFormat = 'dd-MM-yyyy';
    sheet.getRangeByName('A4').setDateTime(DateTime(2014, 03, 14, 14, 14, 14));
     sheet.getRangeByName('A4').numberFormat = 'dd-MM-yyyy';
    sheet.getRangeByName('A5').setDateTime(DateTime(2014, 04, 14, 14, 14, 14));
     sheet.getRangeByName('A5').numberFormat = 'dd-MM-yyyy';
    sheet.getRangeByName('A6').setDateTime(DateTime(2014, 05, 14, 14, 14, 14));
     sheet.getRangeByName('A6').numberFormat = 'dd-MM-yyyy';

    sheet.getRangeByName('B2').setNumber(700);
    sheet.getRangeByName('B3').setNumber(200);
    sheet.getRangeByName('B4').setNumber(300);
    sheet.getRangeByName('B5').setNumber(500);
    sheet.getRangeByName('B6').setNumber(800);
    sheet.getRangeByName('C2').setNumber(30);
    sheet.getRangeByName('C3').setNumber(40);
    sheet.getRangeByName('C4').setNumber(70);
    sheet.getRangeByName('C5').setNumber(2);
    sheet.getRangeByName('C6').setNumber(100);
    final ChartCollection charts = ChartCollection(sheet);
    final Chart chart = charts.add();

    chart.primaryCategoryAxis.numberFormat = 'dd-MM-yyyy'; // When trying this it gives wrong Date: example 01-01-1900

    chart.chartType = ExcelChartType.line;
    chart.dataRange = sheet.getRangeByName('A1:C6');
    chart.isSeriesInRows = false;
    chart.chartTitle = 'Yearly sales';
    chart.chartTitleArea.bold = true;
    chart.chartTitleArea.size = 12;
    chart.legend?.position = ExcelLegendPosition.bottom;
    chart.topRow = 0;
    chart.bottomRow = 20;
    chart.leftColumn = 1;
    chart.rightColumn = 8;
    chart.primaryValueAxis.numberFormat = '0.00';
    final ChartSerie serie = chart.series[0];
    serie.dataLabels.isValue = true;
    serie.dataLabels.isCategoryName = true;
    serie.dataLabels.isSeriesName = true;
    serie.dataLabels.textArea.bold = true;
    serie.dataLabels.textArea.size = 12;
    serie.dataLabels.textArea.fontName = 'Arial';
    sheet.charts = charts;
    List<int> bytes = workbook.saveAsStream();
    File('ChartElement.xlsx').writeAsBytes(bytes);
    workbook.dispose();
