Save a chart as a PNG for web use — grattan_save

A wrapper around grattan_save() that saves a chart as a PNG using the "slide" font (Avenir Next / DM Serif Display) for web-ready output. No PowerPoint or data files are created, and no subdirectory is created.

grattan_save_web(
  filename,
  object = ggplot2::last_plot(),
  type = "normal",
  font = "slide",
  no_new_folder = FALSE,
  ...
)

Arguments

filename: Filename for the chart. Must end in .png (the extension is added automatically if missing; an error is thrown if a different extension is supplied).
object: A ggplot object. Defaults to the last plot created.
type: Chart type - see ?grattan_save for options. Defaults to "normal". All valid grattan_save() types are supported.
font: Default is "slide", appropriate for web purposes.
no_new_folder: Default is FALSE, meaning the chart is saved in a new subdirectory named after filename. If TRUE, no subdirectory is created.
...: Additional arguments passed to grattan_save(), such as height, dpi, force_labs, etc.

Details

Default labelling behaviour for the chosen type is preserved: grattan_save_web() does not force labels on or off.

Examples

if (FALSE) { # \dontrun{
library(ggplot2)
p <- ggplot(mtcars, aes(x = wt, y = mpg)) +
  geom_point() +
  theme_grattan() +
  labs(title = "Web-ready chart",
       subtitle = "Saved as a PNG with the slide font",
       caption = "Source: mtcars")

grattan_save_web("my_chart.png", p, type = "blog")
} # }
