True if the label specified by the DisplayUnit or DisplayUnitCustom property is displayed on the value axis. False if no units are displayed. The default value is True. Read/write Boolean.
Example
This example sets the units on the value axis in myChart to increments of 500 but hides the unit label itself.
With myChart.Axes(xlValue)
.DisplayUnit = xlCustom
.DisplayUnitCustom = 500
.AxisTitle.Caption = "Rebate Amounts"
.HasDisplayUnitLabel = False
End With
