How can I use gganimate with geom_tile?

Question

I was having trouble animating a geom_tile() plot where the tile remains visible after it appears.

Here's my code using the airquality data.

First, the static plot. Here, the x-axis is Day. The y-axis is Month and Temp is the fill.

library(gganimate) 

anim <- ggplot(airquality, aes(x = Day, y = Month, fill = Temp)) +
  geom_tile()

anim

Static Tile Plot

Using transition_reveal() doesn't visually preserve the Temp tiles as it traverses along Day.

anim1 <- anim + transition_reveal(Day)
anim1

Animated Tile Plot

I also tried this with transition_time() with no luck.

Thanks for your help!

One possibility here is transiton_manual:

anim1 <- anim + transition_manual(Day, cumulative = TRUE)

You can achieve this with transition_time() and shadow_mark()

library(gganimate) 

anim <- ggplot(airquality, aes(x = Day, y = Month, fill = Temp)) +
  geom_tile()+ 
  transition_time(Day) +
  shadow_mark()
anim

Similarly, if you find the OP post good, then you could upvote their post as well. That's not only kind, but also you will not receive reps unless their reputation has a certain level. – tjebo Feb 20 '21 at 11:07
