ggplotly doesn't display geom_rect with ymin = -Inf and ymax = Inf

In ggplot::geom_rect(), one can specify the aesthetics ymin = -Inf and ymax = Inf, which will draw the rectangles to the limit of the plotting area. Apparently, ggplotly does not support this behaviour, and will fail to display the rectangles when a ggplot object with such a geom_rect is passed.

Motivation This behaviour of geom_rect is especially useful for indicating time periods of interest when plotting time series. Workarounds such as manually specifying the ymin and ymax limits to mimic the behaviour are much less effective: it can be difficult to know in advance what those limits should be, and they are affected by expand settings in the scale specification.

# Plot definition
example_plot = economics %>%
  ggplot() +
  geom_line(aes(x = date, y = psavert)) +
  geom_rect(data = data.frame(xmin = seq(as.Date('1970-01-01'),
                                         as.Date('2010-01-01'),
                                         '10 years'),
                              xmax = seq(as.Date('1975-01-01'),
                                         as.Date('2015-01-01'),
                                         '10 years'),
                              ymin = -Inf, ymax = Inf),
            aes(xmin = xmin, xmax = xmax, ymin = ymin, ymax = ymax))

# Base ggplot object
example_plot

# Calling ggplotly
example_plot %>% ggplotly()

Commencez par exécuter via ggplotly() l’exemple fourni avec economics et geom_rect, puis suivez le point d’entrée de la conversion ggplotly pour geom_rect. Comparez le ggplot de base et la sortie rendue ; c’est terminé lorsque les rectangles avec ymin = -Inf et ymax = Inf s’affichent jusqu’aux limites de la zone de tracé.
