ggplot2 point fill doesn't translate correctly

还没有人认领这个 Issue。

Summary

aes(color = z) works as expected.

aes(fill = z) does not, and it produces a warning.

Expected behavior

aes(color = z) works as expected.

library(ggplot2)
library(plotly)

set.seed(42)
d <- data.frame(
  x = rnorm(1000),
  y = rnorm(1000),
  z = rnorm(1000)
)

p <- ggplot(d, aes(x, y, color = z)) +
  geom_point(size = 3)

ggplotly(p)

Observed behavior

On the other hand, aes(fill = z) does not work as expected.

There are two issues:

All of the points are the same color
There is a warning message suggesting there's a bug somewhere

p <- ggplot(d, aes(x, y, fill = z)) +
  geom_point(shape = 21, size = 3)

ggplotly(p)

Warning message:
In L$marker$color[idx] <- aes2plotly(data, params, "fill")[idx] :
  number of items to replace is not a multiple of replacement length

首先使用 ggplotly 运行提供的 R 重现，并比较正常工作的颜色映射与失败的 fill 映射。跟踪与替换标记颜色警告相关的 fill 转换；完成标准是 shape-21 点从 z 获得不同的填充，且不出现该警告。
