By default, the AllowInsideFormat property is True. If the AllowInsideFormat property is True, the level displays the new units base on the properties as InsideLabel, InsideUnit and InsideCount. If the AllowInsideFormat property is False, the unit does not display the new time scale unit, instead it displays the label as indicated by OwnerLabel property. In other words, you can use the AllowInsideFormat property on True, when you need to display a new time scale unit, or on False, when actually you need to change the visual appearance for specified unit. Use the SplitBaseLevel property to specify whether the base level is divided in two lines, so the first displays the owner label, and the second line displays the inside format. If the AllowInsideFormat property is False, the grid lines, the inside label, and the tick lines are not shown.

The following VB sample shows how can I change the foreground color for a time unit:

With G2antt1
	.BeginUpdate 
	With .Chart
		.LevelCount = 2
		.FirstVisibleDate = #1/1/2008#
		.AllowInsideZoom = True
		.AllowResizeInsideZoom = False
		.InsideZoomOnDblClick = False
		.DefaultInsideZoomFormat.ForeColor = 255
		With .InsideZooms
			.SplitBaseLevel = False
			.DefaultWidth = 18
			.Add(#1/4/2008#).AllowInsideFormat = False
		End With
	End With
	.EndUpdate 
End With

The following VB.NET sample shows how can I change the foreground color for a time unit:

With AxG2antt1
	.BeginUpdate 
	With .Chart
		.LevelCount = 2
		.FirstVisibleDate = #1/1/2008#
		.AllowInsideZoom = True
		.AllowResizeInsideZoom = False
		.InsideZoomOnDblClick = False
		.DefaultInsideZoomFormat.ForeColor = 255
		With .InsideZooms
			.SplitBaseLevel = False
			.DefaultWidth = 18
			.Add(#1/4/2008#).AllowInsideFormat = False
		End With
	End With
	.EndUpdate 
End With

The following C++ sample shows how can I change the foreground color for a time unit:
