plenv0
: Same as plenv
but if in multiplot
mode does not advance the subpage, instead clears it
plenv0
( | xmin, |
xmax, | |
ymin, | |
ymax, | |
just, | |
axis) ; |
Sets up plotter environment for simple graphs by calling pladv
and
setting up viewport and window to sensible default values. plenv0
leaves enough room around most graphs for axis labels and a title.
When these defaults are not suitable, use the individual routines
plvpas
, plvpor
, or plvasp
for setting up the viewport, plwind
for defining the window, and plbox
for drawing the box.
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
plenv0
using plsvpa
, plvasp
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
, 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

63
: same as 3 except date / time
x
and y

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
