1PLENV(3plplot) PLplot API PLENV(3plplot)
2
6 plenv - Set up standard window and draw box
7
9 plenv(xmin, xmax, ymin, ymax, just, axis)
10
12 Sets up plotter environment for simple graphs by calling pladv(3plplot)
13 and setting up viewport and window to sensible default values.
14 plenv(3plplot) leaves a standard margin (left-hand margin of eight
15 character heights, and a margin around the other three sides of five
16 character heights) around most graphs for axis labels and a title.
17 When these defaults are not suitable, use the individual routines plv‐
18 pas(3plplot), plvpor(3plplot), or plvasp(3plplot) for setting up the
19 viewport, plwind(3plplot) for defining the window, and plbox(3plplot)
20 for drawing the box.
21 Redacted form: plenv(xmin, xmax, ymin, ymax, just, axis)
23 This function is used in example 1,3,9,13,14,19-22,29.
25
27 xmin (PLFLT(3plplot), input)
28 Value of x at left-hand edge of window (in world coordinates).
29 xmax (PLFLT(3plplot), input)
31 Value of x at right-hand edge of window (in world coordinates).
32 ymin (PLFLT(3plplot), input)
34 Value of y at bottom edge of window (in world coordinates).
35 ymax (PLFLT(3plplot), input)
37 Value of y at top edge of window (in world coordinates).
38 just (PLINT(3plplot), input)
40 Controls how the axes will be scaled: -1: the scales will not be
41 set, the user must set up the scale before calling
42 plenv(3plplot) using plsvpa(3plplot), plvasp(3plplot) or other.
43 0: the x and y axes are scaled independently to use as much of
44 the screen as possible. 1: the scales of the x and y axes are
45 made equal. 2: the axis of the x and y axes are made equal, and
46 the plot box will be square.
47 axis (PLINT(3plplot), input)
50 Controls drawing of the box around the plot: -2: draw no box, no
51 tick marks, no numeric tick labels, no axes. -1: draw box only.
52 0: draw box, ticks, and numeric tick labels. 1: also draw coor‐
53 dinate axes at x=0 and y=0. 2: also draw a grid at major tick
54 positions in both coordinates. 3: also draw a grid at minor
55 tick positions in both coordinates. 10: same as 0 except loga‐
56 rithmic x tick marks. (The x data have to be converted to loga‐
57 rithms separately.) 11: same as 1 except logarithmic x tick
58 marks. (The x data have to be converted to logarithms sepa‐
59 rately.) 12: same as 2 except logarithmic x tick marks. (The x
60 data have to be converted to logarithms separately.) 13: same
61 as 3 except logarithmic x tick marks. (The x data have to be
62 converted to logarithms separately.) 20: same as 0 except loga‐
63 rithmic y tick marks. (The y data have to be converted to loga‐
64 rithms separately.) 21: same as 1 except logarithmic y tick
65 marks. (The y data have to be converted to logarithms sepa‐
66 rately.) 22: same as 2 except logarithmic y tick marks. (The y
67 data have to be converted to logarithms separately.) 23: same
68 as 3 except logarithmic y tick marks. (The y data have to be
69 converted to logarithms separately.) 30: same as 0 except loga‐
70 rithmic x and y tick marks. (The x and y data have to be con‐
71 verted to logarithms separately.) 31: same as 1 except loga‐
72 rithmic x and y tick marks. (The x and y data have to be con‐
73 verted to logarithms separately.) 32: same as 2 except loga‐
74 rithmic x and y tick marks. (The x and y data have to be con‐
75 verted to logarithms separately.) 33: same as 3 except loga‐
76 rithmic x and y tick marks. (The x and y data have to be con‐
77 verted to logarithms separately.) 40: same as 0 except date /
78 time x labels. 41: same as 1 except date / time x labels. 42:
79 same as 2 except date / time x labels. 43: same as 3 except
80 date / time x labels. 50: same as 0 except date / time y la‐
81 bels. 51: same as 1 except date / time y labels. 52: same as 2
82 except date / time y labels. 53: same as 3 except date / time y
83 labels. 60: same as 0 except date / time x and y labels. 61:
84 same as 1 except date / time x and y labels. 62: same as 2 ex‐
85 cept date / time x and y labels. 63: same as 3 except date /
86 time x and y labels. 70: same as 0 except custom x and y la‐
87 bels. 71: same as 1 except custom x and y labels. 72: same as
88 2 except custom x and y labels. 73: same as 3 except custom x
89 and y labels.
