    • getColIndex

      int getColIndex()

    • getDataRangeReference

      String getDataRangeReference()

    • getFormula

      default String getFormula()

    • getFormatCode

      String getFormatCode()

    • getPointFormatCode

      default String getPointFormatCode(int index)
      Optional number format for a single data point in the numerical cache.

      Return null when this point has no point-specific format and should inherit the series format from getFormatCode(). Implementations that never use per-point formats can keep the default (null). NumericalCellRangeDataSource is one class that implements this method.

      Parameters:
      index - zero-based point index
      Returns:
      the data point's format code, or null if the underlying class does not support this method or if there is no format code set for this data point.
