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

       This function is used in example 21.

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  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(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.
