Visualize a demand object — plot

Two views of a demand object:

type = "area" (default): aggregated demand – slice values are summed to annual totals and drawn as an area over the years (stacked by region), with the given data years marked as points.
type = "line": profiles – the within-year demand shape by region and year. Slices with an hour tag ("..._h07") are drawn against the hour of day (faceted season x region when a season prefix is present); other calendars fall back to the slice sequence.

Usage

plot_demand(object, type = c("area", "line"), years = NULL, ...)

# S3 method for class 'demand'
autoplot(object, type = c("area", "line"), years = NULL, ...)

Arguments

object: A demand object.
type: "area" (annual totals) or "line" (slice profiles).
years: Optional integer vector of years. For "area" these are the interpolation targets (default: range of the given years); for "line" they filter which given years are shown.
...: Passed to getData() (e.g. region = filter).

Value

A ggplot object (or NULL, invisibly, if there is nothing to plot).
