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

The following VB sample changes the color to show an arbitrary line::

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 color to show an arbitrary line::

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 color to show an arbitrary line::

The following C# sample changes the color to show an arbitrary line::

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";
