      Convert from subnormal coordinates to normalized coord.


Calling Sequence

      subnormal, xsn, ysn, xn, yn


      xsn, ysn = a point in sub-normal coordinates. in
      psn = position parameter in sub-normal coordinates. in

Keyword Parameters


        /CM means that (xsn,ysn) or psn is specified in cm instead
            of sub-normal coordinates.
        WINDOW=n Sets the subwindow to use. Over-rides !p.multi.
            If n > # subwindows then subnormal automatically wraps n.
        /LASTWINDOW uses last plot window.


      xn, yn = point converted to normalized coordinates. out
      subnormal, psn, pn
        pn = position parameter converted to normalized coordinates. out
          where the position parameter has the format: [x1,y1,x2,y2]
          with (x1,y1) being the lower left corner of the plot,
          and (x2,y2) being the upper right corner of the plot.
          If x2 or y2 is 0 (but not both) the plot is forced to be square.

Common Blocks


      Notes: Sub-normal coordinates range from 0 to 1 in the plot sub-area.
        These coordinates arise for multiple plots per pages obtained by
        using !p.multi. The position keyword always works in normalized
        coordinates which always range from 0 to 1 for the entire plot area.
        Ex: subnormal,[.2,.2,.8,.8],p & plot,x,y,position=p
        For multiple page plots subnormal must be called before each plot.
        For single points: subnormal,.3,.7,xn,yn & xyouts,xn,yn,'test',/norm.
          (Must use keyword /norm in xyouts to force normalized coordinates,
            plot position keyword uses normalized coordinates by default).
