Loon's displays that are based on Cartesian coordinates (i.e. scatterplot, histogram and graph display) allow for layering visual information including polygons, text and rectangles.
Usage
l_layer_line(
widget,
x,
y = NULL,
color = "black",
linewidth = 1,
dash = "",
label = "line",
parent = "root",
index = 0,
...
)Arguments
- widget
widget path name as a string
- x
the coordinates of line. Alternatively, a single plotting structure, function or any R object with a plot method can be provided as x and y are passed on to
xy.coords- y
the y coordinates of the line, optional if x is an appropriate structure.
- color
color of line
- linewidth
linewidth of outline
- dash
dash pattern of line, see https://www.tcl-lang.org/man/tcl8.6/TkCmd/canvas.htm#M26
- label
label used in the layers inspector
- parent
group layer
- index
of the newly added layer in its parent group
- ...
additional state initialization arguments, see
l_info_states
Examples
if(interactive()){
p <- l_plot()
l <- l_layer_line(p, x=c(1,2,3,4), y=c(1,3,2,4), color='red', linewidth=2)
l_scaleto_world(p)
# object
p <- l_plot()
l <- l_layer_line(p, x=nhtemp)
l_scaleto_layer(l)
}
