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(),
  text = FALSE,
  text_color = "gray20",
  text_family = getOption("theme_benvi.font_family", "sans"),
  text_size = 3,
  position = "stack",
  position_text = "identity"
)

Arguments

data: A data.frame type object
x: <data-masked> Variable to be mapped in the x-axis.
y: <data-masked> Variable to be mapped in 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: Logical indicating whether a horizontal line crossing the y = 0 axis should be plotted.
order: Logical indicating if the stacked areas should be ordered. Default behavior (TRUE) stacks the largest groups on top.
pal_name: String indicating the name of which palette to use.
scale_name: String indicating fill legend title.
scale_label: String indicating fill legend labels.
text: Logical indicating if text labels should be plotted on column bars
text_color: Color of the text label. Default is "gray20".
text_family: Font of the text label. Defaults to getOption("theme_benvi.font_family", "sans").
text_size: Size of the text label. Default is 3.
position: Argument passed to geom_area.
position_text: Argument passed on to position in geom_text.

Value

A ggplot2 plot

Examples

# Simple area chart
sao_paulo <- subset(iqa, name_muni == "S\u00e3o 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)
