opts_tooltip: Tooltip settings

Description

Settings to be used with girafe() for tooltip customisation.

Usage

opts_tooltip(
  css = NULL,
  offx = 10,
  offy = 0,
  use_cursor_pos = TRUE,
  opacity = 0.9,
  use_fill = FALSE,
  use_stroke = FALSE,
  delay_mouseover = 200,
  delay_mouseout = 500,
  placement = c("auto", "doc", "container"),
  zindex = 999
)

Arguments

css

extra css (added to position: absolute;pointer-events: none;) used to customize tooltip area.

offx, offy

tooltip x and y offset

use_cursor_pos

should the cursor position be used to position tooltip (in addition to offx and offy). Setting to TRUE will have no effect in the RStudio browser windows.

opacity

tooltip background opacity

use_fill, use_stroke

logical, use fill and stroke properties to color tooltip.

delay_mouseover

The duration in milliseconds of the transition associated with tooltip display.

delay_mouseout

The duration in milliseconds of the transition associated with tooltip end of display.

placement

Defines the container used for the tooltip element. It can be one of "auto" (default), "doc" or "container".

• doc: the host document's body is used as tooltip container. The tooltip may cover areas outside of the svg graphic.

• container: the svg container is used as tooltip container. In this case the tooltip content may wrap to fit inside the svg bounds. It will also inherit the CSS styles and transforms applied to the parent containers (like scaling in a slide presentation).

• auto: This is the default, ggiraph choses the best option according to use cases. Usually it redirects to "doc", however in a xaringan context, it redirects to "container".

zindex

tooltip css z-index, default to 999.

Examples

library(ggplot2)

dataset <- mtcars
dataset$carname = row.names(mtcars)

gg <- ggplot(
  data = dataset,
  mapping = aes(x = wt, y = qsec, color = disp,
                tooltip = carname, data_id = carname) ) +
  geom_point_interactive() + theme_minimal()

x <- girafe(ggobj = gg)
x <- girafe_options(x,
  opts_tooltip(opacity = .7,
    offx = 20, offy = -10,
    use_fill = TRUE, use_stroke = TRUE,
    delay_mouseout = 1000) )
if( interactive() ) print(x)
