Create interactive line segments parameterised by location, direction and distance

The geometry is based on ggplot2::geom_spoke(). See the documentation for those functions for more details.

Usage

geom_spoke_interactive(...)

Arguments

...

arguments passed to base function, plus any of the interactive_parameters.

Details for interactive geom functions

The interactive parameters can be supplied with two ways:

• As aesthetics with the mapping argument (via ggplot2::aes()). In this way they can be mapped to data columns and apply to a set of geometries.

• As plain arguments into the geom_*_interactive function. In this way they can be set to a scalar value.

Examples

# add interactive line segments parameterised by location,
# direction and distance to a ggplot -------
library(ggplot2)
library(ggiraph)

df <- expand.grid(x = 1:10, y=1:10)
df$angle <- runif(100, 0, 2*pi)
df$speed <- runif(100, 0, sqrt(0.1 * df$x))

p <- ggplot(df, aes(x, y)) +
  geom_point() +
  geom_spoke_interactive(aes(angle = angle, tooltip=round(angle, 2)), radius = 0.5)
x <- girafe(ggobj = p)
if( interactive() ) print(x)

p2 <- ggplot(df, aes(x, y)) +
  geom_point() +
  geom_spoke_interactive(aes(angle = angle, radius = speed,
                             tooltip=paste(round(angle, 2), round(speed, 2), sep="\n")))
x2 <- girafe(ggobj = p2)
if( interactive() ) print(x2)
