Stacked-area chart of land-cover percentage over time

Draws percentage of area versus year as stacked areas, one band per class (or group), using the official MapBiomas colours, in the style of the MapBiomas coverage figures. Uses ggplot2 when available, otherwise base graphics.

Usage

plot_timeseries(ts, title = NULL, legend = TRUE, lang = c("en", "pt"))

Arguments

ts

A long data frame from cover_timeseries or timeseries_for_species.

title

Optional plot title. If NULL, a title is built from the species/range attributes when present.

legend

Logical; draw the class legend (default TRUE).

lang

Legend language: "en" (default) or "pt". When "en", the band labels use the MapBiomas class_en column (when present in ts) and the axis/legend/title text is in English.

Value

A ggplot object (invisibly) when ggplot2 is available; otherwise NULL after drawing a base plot.
