Description
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

Research direction
Start by running the provided R reproduction with ggplotly and compare the working color mapping with the failing fill mapping. Trace the fill translation associated with the warning about replacing marker colors; done means shape-21 points receive varying fills from z without the warning.
