The CT_FormulaRef complex type specifies the data source reference for a chart ([ISO/IEC29500-1:2016] section 21.2) with filtered series data.<83>

This reference is in the form of a book, sheet, and cell reference. This reference does not include the equals sign.

Child Elements:

sqref: A string element ([XMLSCHEMA2/2] section 3.2.1) that specifies the data source reference for the chart data. This reference MUST follow the ABNF grammar rules defined in Formulas ([MS-XLSX] section 2.2.2) with the following restrictions:

  • MUST follow the ref-nospace-expression rule.

  • MUST NOT use the A1-relative-column and A1-relative-row rules.

  • MUST use only A1-absolute-column and A1-absolute-row.

Contains the data source reference for the series caption or values, or category labels of a filtered out series in the chart.

An application can adjust these cell references when the worksheet layout changes, even when the containing ext element ([ISO/IEC29500-1:2016] section 18.2.7) is not recognized by the application.
