can't add new axis to TChart component

Hi, there
    I got a question for drawing a multi-axis graph. I tried to add a new
axis to TComponent. I wrote my code in  this way:
        TChartAxis*  Axis1=new  TChartAxis(myTChart);
        Axis1->Horizontal=false;
        Axis1->StartPosition=50;
        Axis1->EndPosition=100;
        Axis1->CustomVertAxis=Axis;
     The program compiles and runs. But the newly created axis is drawn on
the original axis. What I need is that the new axis is apart from the
original left axis. I can't figure out how to do that. Please help me to get
the right answer. It may be very easy but I just don't know how.
    Thanks a lot!
