externalData (External Data Relationship)

This element specifies the relationship to the data for this chart.

The data can be linked, pointing to a spreadsheet in another file. Or, the data can be embedded, contained in a separate part within the same xml package containing the chart. In this case, it shall be stored as an embedded Spreadsheet object in Office Open XML format.

This is not used by a spreadsheet application as the spreadsheet application can maintain its own reference to the data in the spreadsheet via the formula <f> element.
