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
.
antialiasN = true|false
(Boolean)
[Default: false
]
axisN = Horizontal|Vertical
(FuncAxis)
Horizontal
and
Vertical
.
[Default: Horizontal
]
colorN = <rrggbb>|red|blue|...
(Color)
The value may be a six-digit hexadecimal number
giving red, green and blue intensities,
e.g. "ff00ff
" for magenta.
Alternatively it may be the name of one of the
pre-defined colors.
These are currently
red
, blue
, green
, grey
, magenta
, cyan
, orange
, pink
, yellow
, black
, white
.
[Default: ff0000
]
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
