Number of characters to wrap the subtitle to. Defaults to 80. Not applicable where mobile equals TRUE.

x_expand

A vector of range expansion constants used to add some padding on the x scale.

x_labels

Adjust the x scale labels through a function or vector.

x_pretty_n

Add balance to the y axis so that zero is in the centre of the y scale.

y_expand

A vector of range expansion constants used to add some padding on the y scale.

y_labels

Adjust the y scale labels through a function or vector.

y_pretty_n

y_title

Y axis title string. Defaults to [Y title].

y_title_wrap

Number of characters to wrap the y title to. Defaults to 50. Not applicable where mobile equals TRUE.

y_trans

A string specifying a transformation for the y axis scale, such as "log10" or "sqrt". Defaults to "identity".

y_zero

TRUE or FALSE of whether the minimum of the y scale is zero. Defaults to TRUE.

y_zero_line

TRUE or FALSE whether to add a zero reference line to the y axis. TRUE if there are positive and negative values in y_var. Otherwise defaults to FALSE.

library(dplyr)

plot_data <- storms %>%
  group_by(year) %>%

ggplot_vbar(plot_data, year, average_wind,
      title = "Average wind speed of Atlantic storms, 1975-2015",
      x_title = "Year",
      y_title = "Average maximum sustained wind speed (knots)")
