    If one does not want to use the default coordinate system used to plot
  into a window (upper left is 0,0), is there a way of changing this 
  coordinate system. For example, I want to use a cartesian coordinate system
  with the center "midwindow". Any information describing how to do this would
  be much appreciated.
