In glyph: A Grammar of Interactive Graphics

Add animation/transition behavior

Description

Add animation/transition behavior

Usage

animate(
  spec,
  transition = "morph",
  duration = 500,
  stagger = 0,
  by = NULL,
  easing = "ease-in-out",
  loop = FALSE
)

Arguments

spec	A glyph_spec
transition	Transition type: "morph", "fade", "slide", "none"
duration	Duration in milliseconds
stagger	Delay between successive marks in ms (for entrance effects)
by	Column that defines animation keyframes. The plot shows one value of it at a time and moves between them, e.g. by = year plays through the years.
easing	Easing function: "linear", "ease-in", "ease-out", "ease-in-out", "bounce", "elastic"
loop	Repeat animation (TRUE, FALSE, or number of times)

Value

Modified glyph_spec

Examples

# Entrance animation: bars grow from baseline
glyph(mtcars, x = cyl, y = mpg) |>
  mark_bar() |>
  animate(transition = "slide", stagger = 50)

# Keyframe animation: morph between groups
glyph(mtcars, x = wt, y = mpg) |>
  mark_point(size = hp, color = cyl) |>
  animate(by = gear, transition = "morph", duration = 800)
