array of references

getAllReferencedVisibleCells

public static List<org.apache.poi.ss.util.CellReference> getAllReferencedVisibleCells(String formula,
 Spreadsheet spreadsheet)

This function uses the getAllReferencedCells function but filters out all the hidden rows from the list honoring filtering of charts based on spreadsheettable filter settings

getAllReferencedCells
