The LinkToWidth property specifies the width for an linkto line. Use the LinkTo property to arbitrary link the current nodes with others.  The PenWidthLinkTo property specifies the width of the links between nodes. The LinkToColor, LinkToPen, LinkToRound, LinkToShowDir property specifies the color, pen, roundness, direction to show an arbitrary link.

The following VB sample changes the width for an arbitrary link:

With ChartView1
	.PenWidthLink = 2
	.LinkColor = 0
	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
		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 changes the width for an arbitrary link:

With AxChartView1
	.PenWidthLink = 2
	.LinkColor = Color.FromArgb(0,0,0)
	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
		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 changes the width for an arbitrary link:

The following C# sample changes the width for an arbitrary link:

axChartView1.PenWidthLink = 2;
axChartView1.LinkColor = Color.FromArgb(0,0,0);
EXORGCHARTLib.Nodes var_Nodes = axChartView1.Nodes;
	var_Nodes.Add("L1_A",0,"LA",null,null).LinkTo = "LB";

	var_Nodes.Add("L2_B2","LB","LB22",null,null);
	var_Nodes.Add("L2_B3","LB","LB23",null,null);

The following VFP sample changes the width for an arbitrary link:

with thisform.ChartView1
	.PenWidthLink = 2
	.LinkColor = 0
	with .Nodes
		.Add("L1_A",0,"LA").LinkTo = "LB"
