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 enough room around most graphs for axis labels
15 and a title. When these defaults are not suitable, use the individual
16 routines plvpas(3plplot), plvpor(3plplot), or plvasp(3plplot) for set‐
17 ting up the viewport, plwind(3plplot) for defining the window, and
18 plbox(3plplot) for drawing the box.
19 Redacted form: plenv(xmin, xmax, ymin, ymax, just, axis)
21 This function is used in example 1,3,9,13,14,19-22.
23
25 xmin (PLFLT, input)
26 Value of x at left-hand edge of window (in world coordinates).
27 xmax (PLFLT, input)
29 Value of x at right-hand edge of window (in world coordinates).
30 ymin (PLFLT, input)
32 Value of y at bottom edge of window (in world coordinates).
33 ymax (PLFLT, input)
35 Value of y at top edge of window (in world coordinates).
36 just (PLINT, input)
38 Controls how the axes will be scaled: -1: the scales will not be
39 set, the user must set up the scale before calling
40 plenv(3plplot) using plsvpa(3plplot), plvasp(3plplot) or other.
41 0: the x and y axes are scaled independently to use as much of
42 the screen as possible. 1: the scales of the x and y axes are
43 made equal. 2: the axis of the x and y axes are made equal, and
44 the plot box will be square.
45 axis (PLINT, input)
48 Controls drawing of the box around the plot: -2: draw no box, no
49 tick marks, no numeric tick labels, no axes. -1: draw box only.
50 0: draw box, ticks, and numeric tick labels. 1: also draw coor‐
51 dinate axes at x=0 and y=0. 2: also draw a grid at major tick
52 positions in both coordinates. 3: also draw a grid at minor
53 tick positions in both coordinates. 10: same as 0 except loga‐
54 rithmic x tick marks. (The x data have to be converted to loga‐
55 rithms separately.) 11: same as 1 except logarithmic x tick
56 marks. (The x data have to be converted to logarithms sepa‐
57 rately.) 12: same as 2 except logarithmic x tick marks. (The x
58 data have to be converted to logarithms separately.) 13: same
59 as 3 except logarithmic x tick marks. (The x data have to be
60 converted to logarithms separately.) 20: same as 0 except loga‐
61 rithmic y tick marks. (The y data have to be converted to loga‐
62 rithms separately.) 21: same as 1 except logarithmic y tick
63 marks. (The y data have to be converted to logarithms sepa‐
64 rately.) 22: same as 2 except logarithmic y tick marks. (The y
65 data have to be converted to logarithms separately.) 23: same
66 as 3 except logarithmic y tick marks. (The y data have to be
67 converted to logarithms separately.) 30: same as 0 except loga‐
68 rithmic x and y tick marks. (The x and y data have to be con‐
69 verted to logarithms separately.) 31: same as 1 except loga‐
70 rithmic x and y tick marks. (The x and y data have to be con‐
71 verted to logarithms separately.) 32: same as 2 except loga‐
72 rithmic x and y tick marks. (The x and y data have to be con‐
73 verted to logarithms separately.) 33: same as 3 except loga‐
74 rithmic x and y tick marks. (The x and y data have to be con‐
75 verted to logarithms separately.)
