Description
Reported first here: Scale_color_manual() labels not working
# insert reprex here
p <- ggplot(mtcars, aes(mpg, wt)) +
geom_point(aes(colour = factor(cyl)))
cols <- c("8" = "red", "4" = "blue", "6" = "darkgreen", "10" = "orange")
p <-
p + scale_colour_manual(
values = cols,
breaks = c("4", "6", "8"),
labels = c("four", "six", "eight")
)

Research direction
Reproduce the supplied mtcars example in R and compare the scale_colour_manual() breaks and labels with the output shown in the linked Plotly examples. No file or test is named, so first locate the scale conversion or rendering entry point; the issue is done when the labels “four”, “six”, and “eight” appear correctly in the rendered plot.
