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

---

double dX1 = gl.X.From;
double dX2 = gl.X.To;

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

TreeNode tnShow = tn.Labels.Label1.GetNode("Show");
//tnShow.nVal = 1;

The following code works.
double dX1 = gl.X.From;
double dX2 = gl.X.To;

---

double dX1 = tr.Root.Scale.From.dVal;
double dX2 = tr.Root.Scale.To.dVal;
