Plot ensemble of forecast realizations — plot

Given a forecast with raw realizations, generate a plot displaying all of them. If the forecast provides simulation numbers (sim column), the ensemble of curves will be plotted. Otherwise, the data will be plotted as points.

Usage

plot_ensemble(plt = NULL, fcst, alpha = 0.3, colour = "black")

Arguments

plt: (Optional) A ggplot object. it will be added to using the + operator. Defaults to NULL, in which case a blank ggplot object will be created.
fcst: A forecast object (see output of create_forecast()).
alpha: (Optional) The alpha parameter to be passed to ggplot2
colour: (Optional) The colour to be passed to ggplot2

Value

A ggplot object.

Examples

plot_ensemble(
  NULL,
  create_forecast(dplyr::tibble(time=rep(1:3,each=3), sim=rep(1:3,3), val=c(4:12))
))


NULL |> plot_ensemble(create_forecast(data.frame(
  time=lubridate::as_datetime(c(0,20000,100000)),
  val=c(20,30,40)
)))
