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

       plsdiplz - Set parameters incrementally (zoom mode) that define current plot-space window

SYNOPSIS

       plsdiplz(xmin, ymin, xmax, ymax)

DESCRIPTION

       Set  relative  minima and maxima incrementally (zoom mode) that define the current plot-space window.  This function has the same effect as
       plsdiplt(3plplot) if that function has not been previously called.  Otherwise, this function implements zoom mode using the  transformation
       min_used = old_min + old_length*min  and max_used = old_min + old_length*max  for each axis.  For example, if min = 0.05 and max = 0.95 for
       each axis, repeated calls to plsdiplz(3plplot) will zoom in by 10 per cent for each call.

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

       This function is used in example 31.

ARGUMENTS

       xmin (PLFLT, input)
	      Relative (incremental) minimum in x.

       ymin (PLFLT, input)
	      Relative (incremental) minimum in y.

       xmax (PLFLT, input)
	      Relative (incremental) maximum in x.

       ymax (PLFLT, input)
	      Relative (incremental) maximum in y.
