info_text(g2, ..., data = NULL, figures = NULL, inherit_asp = TRUE)

info_image(g2, ..., data = NULL, figures = NULL, inherit_asp = TRUE)

info_region(g2, ..., data = NULL, figures = NULL, inherit_asp = TRUE)

info_html(g2, ..., data = NULL, figures = NULL, inherit_asp = TRUE)

info_arc(g2, ..., data = NULL, figures = NULL, inherit_asp = TRUE)

info_data_marker(g2, ..., data = NULL, figures = NULL,
  inherit_asp = TRUE)

info_region_filter(g2, ..., data = NULL, figures = NULL,
  inherit_asp = TRUE)

info_data_region(g2, ..., data = NULL, figures = NULL,
  inherit_asp = TRUE)

Arguments

g2	An object of class g2r as returned by g2r.
...	Info options and asp.
data	A data.frame containing data for asp if NULL is inherited from g2.
figures	Vector of names or indices of figure(s) to apply the information to, if NULL applies only to the first figure.

Examples

g2(mtcars, asp(mpg, qsec)) %>% 
  fig_point() %>% 
  info_data_marker(
    content = "Marker",
    position = c(20, 20),
    inherit_asp = FALSE
  )

newcars <- cars[1:26,]
newcars$text <- LETTERS

g2(cars, asp(speed, dist)) %>% 
  fig_point() %>% 
  info_text(asp(speed, dist, content = text), data = newcars, offsetY = -20)
