By code or via the terminal ? Is it your arrow or not ?

Thanks by your (starting) help.

Is my code. I created it by:

   SetIndexStyle(1,DRAW_ARROW);
   SetIndexArrow(1,233);
   SetIndexBuffer(1,ExtMapBuffer2);
   SetIndexEmptyValue(1,0.0);

And I located it by:

 

   ExtMapBuffer2[i]=Low[i]-a*Point;
