Options

billboard comes with countless options, they are not all listed here. This page merely tries to demonstrate what can be achieved with the package.

Labels & orientation

Add labels and rotate the chart and add a title.

library(dplyr)

mtcars %>% 
  mutate(models = rownames(.)) %>% 
  slice(1:5) %>% 
  b_board(models) %>% 
  b_bar(wt) %>% 
  b_rotate() %>% 
  b_labels() %>% 
  b_title("Rotated chart")

Legend

Change the legend square size and position. Note that you can name each chart added with name

mtcars %>% 
  mutate(models = rownames(.)) %>% 
  slice(1:5) %>% 
  b_board(models) %>% 
  b_bar(wt, name = "weight") %>% 
  b_bar(drat) %>% 
  b_legend(width = 50, height = 20, position = "inset")

Empty

No axis change or legend, change height.

mtcars %>%
  mutate(x = 1:n()) %>% 
  b_board(x) %>% 
  b_spline(wt) %>% 
  b_xaxis(show = FALSE) %>% 
  b_yaxis(show = FALSE) %>% 
  b_size(height = 50) %>% 
  b_legend(show = FALSE)

Mark

Mark lines and regions.

mtcars %>% 
  mutate(x = 1:n()) %>% 
  b_board(x) %>% 
  b_area_spline(drat, name = "Rear axle ratio") %>% 
  b_spline(mpg, axis = "y2") %>% 
  b_grid_line(3, "avg (maybe)", axis = "y") %>% 
  b_region("x", 8, 12)

Color

Customise chart color.

mtcars %>% 
  mutate(x = 1:n()) %>% 
  b_board(x) %>% 
  b_bar(wt) %>% 
  b_area(drat) %>% 
  b_bar(mpg, axis = "y2") %>% 
  b_color_brewer("Accent", 3)

Subchart

Add a subchart

mtcars %>% 
  mutate(x = 1:n()) %>% 
  b_board(x) %>% 
  b_bar(wt) %>% 
  b_area(drat) %>% 
  b_subchart()
