NAME

       plenv - Set up standard window and draw box

SYNOPSIS

       plenv(xmin, xmax, ymin, ymax, just, axis)

DESCRIPTION

       Sets  up  plotter  environment  for simple graphs by calling pladv(3plplot) and setting up
       viewport and window to sensible default values.  plenv(3plplot) leaves enough room  around
       most  graphs  for  axis  labels and a title. When these defaults are not suitable, use the
       individual routines plvpas(3plplot), plvpor(3plplot), or plvasp(3plplot)  for  setting  up
       the  viewport, plwind(3plplot) for defining the window, and plbox(3plplot) for drawing the
       box.

       Redacted form: plenv(xmin, xmax, ymin, ymax, just, axis)

       This function is used in example 1,3,9,13,14,19-22,29.

ARGUMENTS

       xmin (PLFLT, input)
              Value of x at left-hand edge of window (in world coordinates).

       xmax (PLFLT, input)
              Value of x at right-hand edge of window (in world coordinates).

       ymin (PLFLT, input)
              Value of y at bottom edge of window (in world coordinates).

       ymax (PLFLT, input)
              Value of y at top edge of window (in world coordinates).

       just (PLINT, input)
              Controls how the axes will be scaled: -1: the scales will not be set, the user must
              set   up   the   scale   before   calling   plenv(3plplot)  using  plsvpa(3plplot),
              plvasp(3plplot) or other.  0: the x and y axes are scaled independently to  use  as
              much  of the screen as possible.  1: the scales of the x and y axes are made equal.
              2: the axis of the x and y axes are made equal, and the plot box will be square.

       axis (PLINT, input)
              Controls drawing of the box around the plot: -2: draw no box,  no  tick  marks,  no
              numeric  tick labels, no axes.  -1: draw box only.  0: draw box, ticks, and numeric
              tick labels.  1: also draw coordinate axes at x=0 and y=0.  2: also draw a grid  at
              major  tick  positions  in  both  coordinates.   3:  also draw a grid at minor tick
              positions in both coordinates.  10: same as 0 except logarithmic x tick marks. (The
              x  data  have  to  be  converted  to  logarithms separately.)  11: same as 1 except
              logarithmic x  tick  marks.  (The  x  data  have  to  be  converted  to  logarithms
              separately.)  12: same as 2 except logarithmic x tick marks. (The x data have to be
              converted to logarithms separately.)  13: same  as  3  except  logarithmic  x  tick
              marks.  (The  x data have to be converted to logarithms separately.)  20: same as 0
              except logarithmic y tick marks. (The y data have to  be  converted  to  logarithms
              separately.)  21: same as 1 except logarithmic y tick marks. (The y data have to be
              converted to logarithms separately.)  22: same  as  2  except  logarithmic  y  tick
              marks.  (The  y data have to be converted to logarithms separately.)  23: same as 3
              except logarithmic y tick marks. (The y data have to  be  converted  to  logarithms
              separately.)   30:  same  as  0 except logarithmic x and y tick marks. (The x and y
              data have to be  converted  to  logarithms  separately.)   31:  same  as  1  except
              logarithmic  x  and  y  tick  marks.  (The  x  and  y  data have to be converted to
              logarithms separately.)  32: same as 2 except logarithmic x and y tick marks.  (The
              x  and y data have to be converted to logarithms separately.)  33: same as 3 except
              logarithmic x and y tick marks.  (The  x  and  y  data  have  to  be  converted  to
              logarithms  separately.)  40: same as 0 except date / time x labels.  41: same as 1
              except date / time x labels.  42: same as 2 except date / time x labels.  43:  same
              as  3 except date / time x labels.  50: same as 0 except date / time y labels.  51:
              same as 1 except date / time y labels.  52: same as 2 except date / time y  labels.
              53:  same as 3 except date / time y labels.  60: same as 0 except date / time x and
              y labels.  61: same as 1 except date / time x and y labels.  62: same as  2  except
              date  / time x and y labels.  63: same as 3 except date / time x and y labels.  70:
              same as 0 except custom x and y labels.  71: same  as  1  except  custom  x  and  y
              labels.  72: same as 2 except custom x and y labels.  73: same as 3 except custom x
              and y labels.
