Define new text attributes for the label number "labNum".

It allows to do a fine tuning of the labels. All the attributes can be changed, even the label text itself.

Parameters

[in]	labNum	Number of the label to be changed, negative numbers start from the end
[in]	labAngle	New angle value
[in]	labSize	New size (0 erase the label)
[in]	labAlign	New alignment value
[in]	labColor	New label color
[in]	labFont	New label font
[in]	labText	New label text

If an attribute should not be changed just give the value "-1".The following macro gives an example:

{
   c1 = new TCanvas("c1","Examples of Gaxis",10,10,900,500);
   c1->Range(-6,-0.1,6,0.1);
   TGaxis *axis1 = new TGaxis(-5.5,0.,5.5,0.,0.0,100,510,"");
   axis1->SetName("axis1");
   axis1->SetTitle("Axis Title");
   axis1->SetTitleSize(0.05);
   axis1->SetTitleColor(kBlue);
   axis1->SetTitleFont(42);
   axis1->ChangeLabel(1,-1,-1,-1,2);
   axis1->ChangeLabel(3,-1,0.);
   axis1->ChangeLabel(5,30.,-1,0);
   axis1->ChangeLabel(6,-1,-1,-1,3,-1,"6th label");
   axis1->ChangeLabel(-2,-1,-1,-1,3,-1,"2nd to last label");
   axis1->Draw();
}
