Plot an area chart

Usage

plot_area(
  data,
  x,
  y,
  fill = NULL,
  zero = TRUE,
  order = TRUE,
  pal_name = "qual_benvi",
  scale_name = "",
  scale_label = ggplot2::waiver(),
  position = "stack"
)

Arguments

data: A data frame.
x: <data-masked> Variable mapped to the x-axis.
y: <data-masked> Variable mapped to the y-axis.
fill: Fill color for the area. Either a color string (e.g., "blue", "#021841") for a single static color, or a bare column name (without quotes) to map a grouping variable to fill color.
zero: Whether to draw a horizontal line at y = 0.
order: Whether to order stacked areas by size. The default, TRUE, places the largest groups on top.
pal_name: Name of the palette.

scale_label: Fill legend labels.
position: Position adjustment passed to ggplot2::geom_area().

Value

A ggplot object.

Examples

# Simple area chart
sao_paulo <- subset(iqa, name_muni == "São Paulo")
plot_area(data = sao_paulo, x = date, y = index)


# Stacked area chart with fill mapping
total <- subset(iqaiw, rooms == "Total")
plot_area(data = total, x = date, y = index, fill = name_muni)
