    Using Code

    This example code sets Code128 sparkline in the worksheet.

    JavaScript
    Copy Code
    var sheet = spread.getActiveSheet();
    // Set Code128 Barcode Sparkline
    sheet.setValue(3, 1, "Code128", GC.Spread.Sheets.SheetArea.viewport);
    sheet.setValue(3, 2, "465465145645", GC.Spread.Sheets.SheetArea.viewport);
    // Set Style
    sheet.setRowHeight(3, 100);
    for (var col = 1; col < 4; col++)
    {
        sheet.setColumnWidth(col, 200);
    }
    sheet.getRange(3, 0, 1, 4).hAlign(GC.Spread.Sheets.HorizontalAlign.center);
    sheet.getRange(3, 0, 1, 4).vAlign(GC.Spread.Sheets.VerticalAlign.center);
    // Set Formula
    sheet.setFormula(3, 3, '=BC_CODE128(C4)');
