function
Plots an analytic function. This layer is currently only available for the Plane plots (including histogram).
Usage Overview:
layerN=function axisN=Horizontal|Vertical xnameN=<name> fexprN=<expr> colorN=<rrggbb>|red|blue|... thickN=<pixels> dashN=dot|dash|...|<a,b,...> antialiasN=true|false
All the parameters listed here
affect only the relevant layer,
identified by the suffix
N
.
Example:
stilts plot2plane layer1=function fexpr1=sin(x)/x thick1=3 xmin=0 xmax=30 ymin=-0.25 ymax=0.25
antialiasN = true|false
(Boolean)
[Default: false
]
axisN = Horizontal|Vertical
(FuncAxis)
Horizontal
and
Vertical
.
[Default: Horizontal
]
colorN = <rrggbb>|red|blue|...
(Color)
The standard plotting colour names are
red
, blue
, green
, grey
, magenta
, cyan
, orange
, pink
, yellow
, black
, light_grey
, white
.
However, many other common colour names (too many to list here)
are also understood.
The list currently contains those colour names understood
by most web browsers,
from AliceBlue
to YellowGreen
,
listed e.g. in the
Extended color keywords section of
the CSS3 standard.
Alternatively, a six-digit hexadecimal number RRGGBB
may be supplied,
optionally prefixed by "#
" or "0x
",
giving red, green and blue intensities,
e.g. "ff00ff
", "#ff00ff
"
or "0xff00ff
" for magenta.
[Default: red
]
dashN = dot|dash|...|<a,b,...>
(float[])
Possible values for dashed lines are
dot
, dash
, longdash
, dotdash
.
You can alternatively supply a comma-separated list
of on/off length values such as
"4,2,8,2
".
fexprN = <expr>
(String)
thickN = <pixels>
(Integer)
[Default: 1
]
xnameN = <name>
(String)
x
for a horizontal independent variable and
y
for a vertical independent variable,
but any string that is a legal expression language identifier
(starts with a letter, continues with letters, numbers,
underscores) can be used.
[Default: x
