plenv

PLENV(3plplot)							    PLplot API							    PLENV(3plplot)

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 pos-
	      sible.  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  posi-
	      tions  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  con-
	      verted  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.
