NAME

       plgspa - Get current subpage parameters

SYNOPSIS

       plgspa(xmin, xmax, ymin, ymax)

DESCRIPTION

       Gets  the size of the current subpage in millimeters measured from the bottom left hand corner of the output device page or screen.  Can be
       used in conjunction with plsvpa(3plplot) for setting the size of a viewport in absolute coordinates (millimeters).

       Redacted form: plgspa(xmin, xmax, ymin, ymax)

       This function is used in example 23.

ARGUMENTS

       xmin (PLFLT *, output)
	      Pointer to variable with position of left hand edge of subpage in millimeters.

       xmax (PLFLT *, output)
	      Pointer to variable with position of right hand edge of subpage in millimeters.

       ymin (PLFLT *, output)
	      Pointer to variable with position of bottom edge of subpage in millimeters.

       ymax (PLFLT *, output)
	      Pointer to variable with position of top edge of subpage in millimeters.

NAME

       plvpas - Specify viewport using coordinates and aspect ratio

SYNOPSIS

       plvpas(xmin, xmax, ymin, ymax, aspect)

DESCRIPTION

       Device-independent  routine  for  setting  up the viewport.  The viewport is chosen to be the largest with the given aspect ratio that fits
       within the specified region (in terms of normalized subpage coordinates).  This routine is functionally equivalent to plvpor(3plplot)  when
       a ``natural'' aspect ratio (0.0) is chosen.  Unlike plvasp(3plplot), this routine reserves no extra space at the edges for labels.

       Redacted form: plvpas(xmin, xmax, ymin, ymax, aspect)

       This function is used in example 9.

ARGUMENTS

       xmin (PLFLT, input)
	      The normalized subpage coordinate of the left-hand edge of the viewport.

       xmax (PLFLT, input)
	      The normalized subpage coordinate of the right-hand edge of the viewport.

       ymin (PLFLT, input)
	      The normalized subpage coordinate of the bottom edge of the viewport.

       ymax (PLFLT, input)
	      The normalized subpage coordinate of the top edge of the viewport.

       aspect (PLFLT, input)
	      Ratio of length of y axis to length of x axis.
