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

    Thanks, at least for the time being, you can do something like this instead:

    plot_ly(d, x = ~x, y = ~y, color = ~z, colors = "Blues", stroke = I("black"), size = I(10), span = I(1))

    Thanks for the suggestion! Unfortunately, it didn't work for me.

    Here's what I get:

    plot_ly(
  data = d,
  x = ~x,
  y = ~y,
  color = ~z,
  colors = "Blues",
  stroke = I("black"),
  size = I(10),
  span = I(1)
)

    You'll need the development version devtools::install_github('ropensci/plotly')

    As an alternative work around I changed the points from fill to color and then increased the stroke enough that the circle gets coloured in. Shouldn't need the development version or the plotly code.

    `geom_point(data=someDF, aes(x=X,y=Y, color = n), pch=21, size = 4)

    to

    `geom_point(data = someDF, aes(x=X,y=Y, color = n), pch=21, size = 2, stroke = 2)

    First thanks for bringing plotly to R! We love it!

    I wonder whether it is related to the fact that color for geom_point with shape=21~25 which have stroke, defines the stroke color; for other shapes that don't have stroke, color defines the fill color. Therefore the complication of translating color from ggplot to plotly.

    See the fill option for the bottom plot here:
    https://ggplot2.tidyverse.org/reference/scale_shape.html

    I just want to add the observation that fill with continuous color scale doesn't seem to work, but with discrete color scale does.

    library(ggplot2)
library(plotly)

set.seed(42)
d <- data.frame(
  x = rnorm(1000),
  y = rnorm(1000),
  z2 = sample(3, 1000, TRUE)
)

p <- ggplot(d, aes(x, y, fill=as.factor(z2))) +
  geom_point(shape=21, size = 3, color="yellow") + scale_fill_manual(values=c("black", "blue", "red"))

ggplotly(p)

    I have the same problem (plus I need another variable for the size argument). I solved using color instead of fill as sahirmoosvi suggested, but instead of using the stroke argument, I set shape = 16 so a filled circle. The only problem is you can't set the points border color.

    Still an issue with plotly=4.10.1 and ggplot2=3.4.0.

    Having the same issue - ggplotly with scale_color_gradient works as expected but fails when using scale_fill_gradient. Have left a comment here #606 but this thread here is actually even more applicable to my problem.
