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 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

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.

position

Argument passed to geom_area.

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)
