Re: Generating an Excel chart

[jmcnamara]

Spreadsheet::WriteExcel provides a utility function called xl_range_formula()to deal with this.

See the Working with cell ranges section of the chart documentation:

    $chart->add_series(
        categories    => xl_range_formula( 'Sheet1', 1, 9, 0, 0 ),
        values        => xl_range_formula( 'Sheet1', 1, 9, 1, 1 ),
    );

Note, if you are creating an Excel 2007 workbook and chart then you could consider using Excel::Writer::XLSX. It has a slightly easier interface for this case:

    $chart->add_series( categories => '=Sheet1!$A$2:$A$7'      ); # Sa
+me as ...
    $chart->add_series( categories => [ 'Sheet1', 1, 6, 0, 0 ] ); # Ze
+ro-indexed.
