    DataMatrix barcode is a high density, two-dimensional barcode with square modules typically arranged in a square or a rectangular matrix pattern.

    A screenshot depicting datamatrix barcode sparkline is shared below.

    Formula definition

    You can set Datamatrix sparkline in a worksheet using the following formula:

    =BC_DataMatrix(value, color, backgroudColor, eccMode, ecc200SymbolSize, ecc200EndcodingMode, ecc00_140Symbole, structureAppend, structureNumber, fileIdentifier, quietZoneRight, quietZoneTop, quietZoneBottom)

    Parameter

    Name Description
    value A string that represents encode on the symbol of QRCode.
    color A color that represents the barcode color. The default value is 'rgb(0,0,0)'.
    backgroundColor A color that represents the barcode backgroundcolor. The default value is 'rgb(255, 255, 255)'
    eccMode A value that represents which ecc mode to use. It has the following values : 'ECC000, ECC050, ECC080, ECC100, ECC140, ECC200'.
    ecc200SymbolSize A value that specifies the size of the ECC200 symbol only. The default value is 'squareAuto'.
    ecc200EndcodingMode A value that specifies which encoding mode to use for the symbol. The default value is 'auto'.
    ecc00_140Symbole A value that specifies the size of the ECC000-140 symbol only. The default value is 'auto'.
    structureAppend Specifies whether the symbol is part of a structured append message ECC200 only.The default value is 'false'.
    structureNumber A value that represents which block the symbol is in the structured append message. It has the value '0-15', only for ECC200. The default value is '0'.
    fileIdentifier A value that specifies the file identification. It has values '1-254', only for ECC200. The default value is '0'.
    quietZoneRight A value that represents the size of right quiet zone.
    quietZoneTop A value that represents the size of top quiet zone.
    quietZoneBottom A value that represents the size of bottom quiet zone.

    Using Code

    This example creates a DataMatrix barcode sparkline.

    JavaScript
    Copy Code
    var sheet = spread.getActiveSheet();
    // Datamatrix sets the barcode sparkline
    sheet.setValue(3, 1, "Data Matrix", GC.Spread.Sheets.SheetArea.viewport);
    sheet.setValue(3, 2, "Policy:411", GC.Spread.Sheets.SheetArea.viewport);
    // Set the 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 the Formula
    sheet.setFormula(3, 3, '=BC_DataMatrix(C4)');
