NAME

       plenv0  -  Same  as  plenv(3plplot) but if in multiplot mode does not advance the subpage,
       instead clears it

SYNOPSIS

       plenv0(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.  plenv0(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: plenv0(xmin, xmax, ymin, ymax, just, axis)

       This function is used in example 21.

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   plenv0(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.
