By default, the ShowLinkDir property is True. This property has effect only if the ShowLinksDir property of the ChartView is True. You can use the ShowLinkDir property to hide specific arrows in the chart.

The following samples shows how to hide directions for specific links:

VBA (MS Access, Excell...)

With ChartView1
	.IndentSiblingY = 30
	.ShowLinksDir = True
	.PenWidthLink = 2
	.LinkColor = RGB(0,0,0)
	.AntiAliasing = True
	With .Nodes
		.Add("L1_A",0,"LA").ShowLinkDir = False
		.Add "L1_B",0,"LB"
		.Add "L2_A","LA","LA2"
		.Add "L2_B","LB","LB2"
	End With
End With

VB6

With ChartView1
	.IndentSiblingY = 30
	.ShowLinksDir = True
	.PenWidthLink = 2
	.LinkColor = RGB(0,0,0)
	.AntiAliasing = True
	With .Nodes
		.Add("L1_A",0,"LA").ShowLinkDir = False
		.Add "L1_B",0,"LB"
		.Add "L2_A","LA","LA2"
		.Add "L2_B","LB","LB2"
	End With
End With

VB.NET

With Exchartview1
	.IndentSiblingY = 30
	.ShowLinksDir = True
	.PenWidthLink = 2
	.LinkColor = Color.FromArgb(0,0,0)
	.AntiAliasing = True
	With .Nodes
		.Add("L1_A",0,"LA").ShowLinkDir = False
		.Add("L1_B",0,"LB")
		.Add("L2_A","LA","LA2")
		.Add("L2_B","LB","LB2")
	End With
End With

VB.NET for /COM
