  1. With a mouse, just press and hold the 
     left-mouse button and move mouse.

  2. From your "CINT command prompt"/macro/C/C++ code.
     TPad class is supplied with two methods to change the Pad 
     objects:

     void TPad::SetPad(const Text_t *name, const Text_t *title,
                  Float_t xlow, Float_t ylow, Float_t xup, Float_t
                  yup, Color_t color, Short_t bordersize, Short_t
                  bordermode)
  
     void TPad::SetPad(Float_t xlow, Float_t ylow, Float_t xup, 
                      Float_t yup) 

   (see http://root.cern.ch/root/html/TPad.html)
     I guess you need second one.

   I'd like to call your attention that all "size" parameters are 
floats and must be normalized (NDC), i.e. they must be >=0.0 and <= 
1.0. One cab watch the current parameters of the Pad with Inspect() 
method and via Status Bar (Select Canvas menu -> Options -> Status 
Bar)

     Hope this helps,
