The LinkToShowDir property specifies the whether the link shows its direction . Use the LinkTo property to arbitrary link the current nodes with others.  The ShowLinksDir property specifies whether the links between nodes shows the direction. The LinkToWidth, LinkToColor, LinkToRound, LinkToPen property specifies the width, color, roundness, pen to show an arbitrary link.

The following VB sample shows the direction for an arbitrary link only:

With ChartView1
	.ShowLinksDir = False
	.PenWidthLink = 2
	.LinkColor = 0
	.AntiAliasing = True
	With .Nodes
		.Add("L1_A",0,"LA").LinkTo = "LB"
		With .Add("L1_B<br><br>Cust",0,"LB")
			.LinkTo = "LA2"
			.LinkToColor("LA2") = RGB(255,0,0)
			.LinkToWidth("LA2") = 2
			.LinkToPen("LA2") = exPenDashDot
			.LinkToShowDir("LA2") = True
		End With
		.Add "L2_A","LA","LA2"
		.Add "L2_B1","LB","LB21"
		.Add "L2_B2","LB","LB22"
		.Add "L2_B3","LB","LB23"
	End With
End With

The following VB.NET sample shows the direction for an arbitrary link only:

With AxChartView1
	.ShowLinksDir = False
	.PenWidthLink = 2
	.LinkColor = Color.FromArgb(0,0,0)
	.AntiAliasing = True
	With .Nodes
		.Add("L1_A",0,"LA").LinkTo = "LB"
		With .Add("L1_B<br><br>Cust",0,"LB")
			.LinkTo = "LA2"
			.LinkToColor("LA2") = 255
			.LinkToWidth("LA2") = 2
			.LinkToPen("LA2") = EXORGCHARTLib.PenTypeEnum.exPenDashDot
			.LinkToShowDir("LA2") = True
		End With
		.Add "L2_A","LA","LA2"
		.Add "L2_B1","LB","LB21"
		.Add "L2_B2","LB","LB22"
		.Add "L2_B3","LB","LB23"
	End With
End With

The following C++ sample shows the direction for an arbitrary link only:
