Create interactive textual annotations

The geometries are based on ggplot2::geom_text() and ggplot2::geom_label(). See the documentation for those functions for more details.

Usage

geom_label_interactive(...)

geom_text_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 labels to a ggplot -------
library(ggplot2)
library(ggiraph)


p <- ggplot(mtcars, aes(wt, mpg, label = rownames(mtcars))) +
  geom_label_interactive(aes(tooltip = paste(rownames(mtcars), mpg, sep = "\n")))
x <- girafe(ggobj = p)
if( interactive() ) print(x)


p <- ggplot(mtcars, aes(wt, mpg, label = rownames(mtcars))) +
  geom_label_interactive(aes(fill = factor(cyl),
                             tooltip = paste(rownames(mtcars), mpg, sep = "\n")),
                         colour = "white",
                         fontface = "bold")
x <- girafe(ggobj = p)
if( interactive() ) print(x)

# add interactive texts to a ggplot -------
library(ggplot2)
library(ggiraph)

## the data
dataset = mtcars
dataset$label = row.names(mtcars)

dataset$tooltip = paste0( "cyl: ", dataset$cyl, "<br/>",
       "gear: ", dataset$gear, "<br/>",
       "carb: ", dataset$carb)

## the plot
gg_text = ggplot(dataset,
                 aes(x = mpg, y = wt, label = label,
                     color = qsec,
                     tooltip = tooltip, data_id = label)) +
  geom_text_interactive(check_overlap = TRUE) +
  coord_cartesian(xlim = c(0,50))

## display the plot
x <- girafe(ggobj = gg_text)
x <- girafe_options(x = x,
                    opts_hover(css = "fill:#FF4C3B;font-style:italic;") )
if( interactive() ) print(x)
