Plot a backtest object — plot.Backtest • lossratio

Visualise the A/E Error (ae_err) of a "Backtest" object.

Three plot types:

"col": A/E Error aggregated by development period (one line per summary statistic).
"diag": A/E Error aggregated by calendar diagonal.
"cell": per-cell A/E Error as a scatter / line, faceted by group.

Usage

# S3 method for class 'Backtest'
plot(
  x,
  type = c("col", "diag", "cell"),
  cell_type = c("cumulative", "incremental"),
  scales = c("fixed", "free_y", "free_x", "free"),
  theme = c("view", "save", "shiny"),
  ...
)

Arguments

x: An object of class "Backtest".
type: Plot type. One of "col", "diag", "cell".
cell_type: Which projection view to display. One of "cumulative" (default; uses ae_err) or "incremental" (uses incr_ae_err). Both are stored on every Backtest object – pick the view at plot time.
scales: Facet scale argument. One of "fixed", "free", "free_x", "free_y".
theme: String passed to .switch_theme().
...: Extra arguments passed to .switch_theme().
