[ROOT] Drawing many points of Array X[n], Y[n] without using TGraph...

Dear Rooters,

How do we draw many points on the Pad represented by N elements of X[N] 
and Y[N] with out using the TGraph? 

By TGraph the drawing is straight-forward, however I want to draw other 
objects like a box, line, etc..., and I want to optimize space. By 
optimize, I mean that for example "just" after the point mark by "@", 
there  is a box. The distance of the box and the point "@" is close , but 
because of the vertical margin B, the Box cannot be drawn near "@". The 
Box seems to appear at P2 because of the margin B of TGraph.

I want something like:
    Draw a Point/Box at coordinates (xp,yp) of the Pad. From it I am  
free to move the box or any point closer or farther from point "@" by 
specifying their coordinates (xp,yp).

Thanks for your time.
