Remarks

The ColumnNameID, DisplayWidth, DisplayOrder, and Mapped attributes determine the appearance of the data column itself in the External Data window.

The remaining attributes determine how Visio displays and formats the data in the column in the External Data window, how Visio displays the data when it is linked to a shape, and how Visio uses the data in internal calculations.
