To specify how to deal with missing data for a chart, choose Chart Tools➜Design➜Data➜Select
Data. In the Select Data Source, click the Hidden and Empty Cells button. Excel displays its
Hidden and Empty Cell Settings dialog box. Make your choice in the dialog box. The option that
you select applies to the entire chart, and you can’t set a different option for different series in
the same chart.
Normally, a chart doesn’t display data that’s in a hidden row or columns. You can use the Hidden
and Empty Cell Settings dialog box to force a chart to use hidden data.
