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 a standard margin  (left-hand  margin  of  eight
       character  heights,  and  a  margin  around  the other three sides of five character heights) 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(3plplot), input)
              Value of x at left-hand edge of window (in world coordinates).

       xmax (PLFLT(3plplot), input)
              Value of x at right-hand edge of window (in world coordinates).

       ymin (PLFLT(3plplot), input)
              Value of y at bottom edge of window (in world coordinates).

       ymax (PLFLT(3plplot), input)
              Value of y at top edge of window (in world coordinates).

       just (PLINT(3plplot), 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(3plplot), 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.
