Map a column to marker size — set

Scales each marker by the value of a numeric column, turning a scatterplot into a bubble chart. Only scatterplots draw markers, so this does not apply to the other chart types.

Usage

set_size(chart, size, range = NULL, scale = "linear")

Arguments

chart: Defines which chart to modify.
size: Defines which numeric column the marker sizes are drawn from.
range: default NULL. Defines the smallest and largest marker size as a length-2 numeric vector. NULL keeps the SDK's own 5 to 30.
scale: default "linear". Defines how values map onto that range, either "linear" or "log".

Value

chart, with its marker sizes set.

Examples

df <- data.frame(len = c(1, 5, 3), dep = c(2, 4, 6), mass = c(10, 40, 25))

arc_scatter(df, len, dep) |>
  set_size(mass, range = c(4, 20))
