view_follow: Let the view follow the data in each frame

Description

This view will set the panels to include the data present in the frame.

Usage

view_follow(
  fixed_x = FALSE,
  fixed_y = FALSE,
  exclude_layer = NULL,
  aspect_ratio = 1
)

Arguments

fixed_x, fixed_y

Either a logical indicating if the dimension should not be modified by the view, or a numeric vector giving the lower and upper bounds of the dimension. For the latter, an NA value will be substituted for whatever is calculated by the view (e.g. fixed_x = c(0, NA)) will fix the minimum x value to 0 and let the view calculate the upper bound.

exclude_layer

Integer vector of layer indices that should be ignored when calculating the view

aspect_ratio

If the coord is fixed, ensure that the view matches the given aspect ratio. Will override anything given in fixed_x/fixed_y

Examples

anim <- ggplot(iris, aes(Sepal.Length, Sepal.Width)) +
  geom_point() +
  labs(title = "{closest_state}") +
  transition_states(Species, transition_length = 4, state_length = 1) +
  view_follow()

# Fixing a dimension can be done in general
anim1 <- ggplot(iris, aes(Sepal.Length, Sepal.Width)) +
  geom_point() +
  labs(title = "{closest_state}") +
  transition_states(Species, transition_length = 4, state_length = 1) +
  view_follow(fixed_x = TRUE)

# ...or just for one side of the range
anim1 <- ggplot(iris, aes(Sepal.Length, Sepal.Width)) +
  geom_point() +
  labs(title = "{closest_state}") +
  transition_states(Species, transition_length = 4, state_length = 1) +
  view_follow(fixed_x = c(4, NA), fixed_y = c(2, NA))
