animated ggplotly: geoms contesting visibility when plotted on same mappings

Cannot plot geom_point and geom_line on same mappings in animated ggplotly()

Creating a ggplot object (with frame) and calling in ggplotly(). I expect to be able to view geom_point and geom_text mapped to the variables. I sometimes observe one being displayed on more frames while the other flys in from the top left in one or few frames.

work around: add sub-pixel changes to one or both geoms till working.

library(ggplot2)
library(plotly)

rn <- data.frame(rn = 1:5)
x  <- data.frame(scale(mtcars), lab=abbreviate(rownames(mtcars),2))
x_cross <- merge(x, rn, all = TRUE) # cross join

# Only text or points show, not both 
gg1 <- ggplot() + 
  geom_text(data=x_cross, mapping = aes(x=disp, y=hp, label=lab, frame=rn)) +
  geom_point(data=x_cross, mapping = aes(x=disp,  y=hp, frame=rn),color="red") + 
  theme_void()
gg1
ggplotly(gg1)

# Text and points show for all frames
gg2 <- ggplot() + 
  geom_text(data=x_cross, mapping = aes(x=disp+.1*rn, y=hp, label=lab, frame=rn)) +
  geom_point(data=x_cross, mapping = aes(x=disp+.1*rn,  y=hp, frame=rn),color="red") + 
  theme_void()
gg2
ggplotly(gg2)

# tooltip = "none", changes behaviour, points don't show up.
ggplotly(gg2, tooltip = "none")

首先，使用 ggplotly() 运行所提供的 R 复现代码，比较动画 geom_text 和 geom_point 在各帧之间以及 tooltip = "none" 时的表现。跟踪动画 ggplotly 的转换和渲染路径；完成标准是两个 geom 在每一帧中都保持可见，且坐标没有子像素级变化，同时已理解或修正所报告的 tooltip 行为。
