DisplayUnitLabel interface
Office 2013 and later
Represents a unit label on an axis in the specified chart.
Namespace: Microsoft.Office.Interop.Excel
Assembly: Microsoft.Office.Interop.Excel (in Microsoft.Office.Interop.Excel.dll)
Unit labels are useful for charting large values — for example, in the millions or billions. You can make the chart more readable by using a single unit label instead of large numbers at each tick mark.
Use the DisplayUnitLabel property to return the DisplayUnitLabel object.
