Hi,

I'm facing a weird issue when trying to access axis tree.

[code]void add_special_tick(double dTick, string strTick)
{
	GraphLayer gl = Project.ActiveLayer();
	if (gl)
	{
		Axis axesX = gl.XAxis;
		Scale scX(gl.X);
		Tree tr;
		
		tr = axesX.GetFormat(FPB_ALL, FOB_ALL, true, true);
		
		tr.Root.NewAxes.NewAxis2.Specials.SpecialCount.nVal = 1;
		tr.Root.NewAxes.NewAxis2.Specials.Specials.Special1.Type.nVal = 35;
		tr.Root.NewAxes.NewAxis2.Specials.Specials.Special1.Value.dVal = dTick;
		tr.Root.NewAxes.NewAxis2.Specials.Specials.Special1.EnableLabel.nVal = 1;
		tr.Root.NewAxes.NewAxis2.Specials.Specials.Special1.Label.strVal = strTick;
		
		double dX1 = scX.From;
		double dX2 = scX.To;
		double dTol = (dX2 - dX1) / 20;
		
		TreeNodeCollection tnc(tr.Root.NewAxes.NewAxis2.RefLines.RefLines, "RefLine");
		foreach (TreeNode tn in tnc)
		{
			if (dTick + dTol > tn.Value.dVal && dTick - dTol < tn.Value.dVal) 
				tn.Labels.Label1.Show.nVal = 0;
		}
		
		if (0 == axesX.UpdateThemeIDs(tr.Root))
		{
			bool bRet = axesX.ApplyFormat(tr, true, true);
		}
	}
}[/code]

1st Issue:
If I want to get axis from and to, I need to use Scale object
If I try to read tr.Root.Scale.From.dVal or tr.Root.Scale.To.dVal, I get an error saying that those variables are not declared.
Why that ?
When debugging, I can see that they exist
Moreover, it's a treenode, so compiler shouldn't care whether that leaf exists or not

2nd issue:
The function will add a special tick with label in a graph that has a few reflines with labels.
If the special tick is near reflines labels, I will hide them
Here again, I have an error saying that tn.Labels.Label1.Show.nVal is not declared

Thanks for the help

You may show an example of this very issue. quote: 2nd issue: The function will add a special tick with label in a graph that has a few reflines with labels.

You have to write the code similar to this: TreeNode tnShow = tn.Labels.Label1.GetNode("Show"); //tnShow.nVal = 1; ------------------------------------------ Be The Change You Want To See In The World ------------------------------------------
