1PLENV0(3plplot) PLplot API PLENV0(3plplot)
2
6 plenv0 - Same as plenv(3plplot) but if in multiplot mode does not
7 advance the subpage, instead clears it.
8
10 plenv0(xmin, xmax, ymin, ymax, just, axis)
11
13 Sets up plotter environment for simple graphs by calling pladv(3plplot)
14 and setting up viewport and window to sensible default values.
15 plenv0(3plplot) leaves enough room around most graphs for axis labels
16 and a title. When these defaults are not suitable, use the individual
17 routines plvpas(3plplot), plvpor(3plplot), or plvasp(3plplot) for set‐
18 ting up the viewport, plwind(3plplot) for defining the window, and
19 plbox(3plplot) for drawing the box.
20 Redacted form: plenv0(xmin, xmax, ymin, ymax, just, axis)
22 This function is used in example 21.
24
26 xmin (PLFLT, input)
27 Value of x at left-hand edge of window (in world coordinates).
28 xmax (PLFLT, input)
30 Value of x at right-hand edge of window (in world coordinates).
31 ymin (PLFLT, input)
33 Value of y at bottom edge of window (in world coordinates).
34 ymax (PLFLT, input)
36 Value of y at top edge of window (in world coordinates).
37 just (PLINT, input)
39 Controls how the axes will be scaled: -1: the scales will not be
40 set, the user must set up the scale before calling
41 plenv0(3plplot) using plsvpa(3plplot), plvasp(3plplot) or other.
42 0: the x and y axes are scaled independently to use as much of
43 the screen as possible. 1: the scales of the x and y axes are
44 made equal. 2: the axis of the x and y axes are made equal, and
45 the plot box will be square.
46 axis (PLINT, input)
49 Controls drawing of the box around the plot: -2: draw no box, no
50 tick marks, no numeric tick labels, no axes. -1: draw box only.
51 0: draw box, ticks, and numeric tick labels. 1: also draw coor‐
52 dinate axes at x=0 and y=0. 2: also draw a grid at major tick
53 positions in both coordinates. 3: also draw a grid at minor
54 tick positions in both coordinates. 10: same as 0 except loga‐
55 rithmic x tick marks. (The x data have to be converted to loga‐
56 rithms separately.) 11: same as 1 except logarithmic x tick
57 marks. (The x data have to be converted to logarithms sepa‐
58 rately.) 12: same as 2 except logarithmic x tick marks. (The x
59 data have to be converted to logarithms separately.) 13: same
60 as 3 except logarithmic x tick marks. (The x data have to be
61 converted to logarithms separately.) 20: same as 0 except loga‐
62 rithmic y tick marks. (The y data have to be converted to loga‐
63 rithms separately.) 21: same as 1 except logarithmic y tick
64 marks. (The y data have to be converted to logarithms sepa‐
65 rately.) 22: same as 2 except logarithmic y tick marks. (The y
66 data have to be converted to logarithms separately.) 23: same
67 as 3 except logarithmic y tick marks. (The y data have to be
68 converted to logarithms separately.) 30: same as 0 except loga‐
69 rithmic x and y tick marks. (The x and y data have to be con‐
70 verted to logarithms separately.) 31: same as 1 except loga‐
71 rithmic x and y tick marks. (The x and y data have to be con‐
72 verted to logarithms separately.) 32: same as 2 except loga‐
73 rithmic x and y tick marks. (The x and y data have to be con‐
74 verted to logarithms separately.) 33: same as 3 except loga‐
75 rithmic x and y tick marks. (The x and y data have to be con‐
76 verted to logarithms separately.) 40: same as 0 except date /
77 time x labels. 41: same as 1 except date / time x labels. 42:
78 same as 2 except date / time x labels. 43: same as 3 except
79 date / time x labels. 50: same as 0 except date / time y
80 labels. 51: same as 1 except date / time y labels. 52: same as
81 2 except date / time y labels. 53: same as 3 except date / time
82 y labels. 60: same as 0 except date / time x and y labels. 61:
83 same as 1 except date / time x and y labels. 62: same as 2
84 except date / time x and y labels. 63: same as 3 except date /
85 time x and y labels. 70: same as 0 except custom x and y
86 labels. 71: same as 1 except custom x and y labels. 72: same
87 as 2 except custom x and y labels. 73: same as 3 except custom
88 x and y labels.
