Plot a Total object as a per-group bar chart

Visualise an object of class Total as a horizontal bar chart, with one bar per group. Because Total has no time dimension, this is a simple group-level comparison of the chosen metric (loss ratio, total loss, etc.) rather than a trajectory.

Usage

# S3 method for class 'Total'
plot(
  x,
  value_var = "lr",
  amount_divisor = 1e+08,
  theme = c("view", "save", "shiny"),
  ...
)

Arguments

x: An object of class Total.
value_var: A single metric to plot. Must be one of the columns carried by a Total: "lr", "loss", "rp", "loss_prop", or "rp_prop". Default "lr".
amount_divisor: Numeric scaling factor used only for y-axis labels of amount variables. Default 1e8.
theme: A string passed to .switch_theme() ("view", "save", "shiny").
...: Additional arguments passed to .switch_theme().

Value

A ggplot object.

Details

Bars are ordered by the value of value_var (descending). When more than one grouping variable is present, an interaction is used as the bar identifier.

Ratio and proportion metrics are plotted on the original scale and labelled as percentages. Amount metrics are plotted on the original scale and labelled using amount_divisor.

Examples

if (FALSE) { # \dontrun{
tot <- build_total(df, group_var = cv_nm)
plot(tot)
plot(tot, value_var = "loss")
} # }
