Universal ggplot block with selectable visualization types — new_ggplot

A flexible block that allows users to select from various ggplot2 geoms and dynamically shows relevant aesthetics for the selected visualization.

Usage

new_ggplot_block(
  type = "point",
  x = character(),
  y = character(),
  color = character(),
  fill = character(),
  size = character(),
  shape = character(),
  linetype = character(),
  group = character(),
  alpha = character(),
  density_alpha = 0.8,
  position = "stack",
  bins = 30,
  donut = FALSE,
  ...
)

Arguments

type: Initial chart type (default "point"). Options: "point", "bar", "line", "boxplot", "violin", "density", "area", "histogram", "pie"
x: Column for x-axis
y: Column for y-axis
color: Column for color aesthetic
fill: Column for fill aesthetic
size: Column for size aesthetic
shape: Column for shape aesthetic
linetype: Column for linetype aesthetic
group: Column for group aesthetic
alpha: Column for alpha aesthetic (variable transparency)
density_alpha: Fixed alpha value for density plots (default 0.8)
position: Position adjustment for certain geoms
bins: Number of bins for histogram
donut: Whether to create donut chart when type is "pie" (default FALSE)
...: Forwarded to new_plot_block

Value

A plot block object of class ggplot_block.
