I have a problem with a plot with a number of subplots, which all have the same legend entries. I want to show the legend entries only once for each color/name. How can I avoid this behaviour?
library(tidyr)
library(plotly)
mpg %>%
group_by(class) %>%
do(p = plot_ly(., x = ~cyl, y = ~displ, color = ~trans, type = 'bar')) %>%
subplot(nrows = 2, shareX = TRUE, titleX = TRUE) %>%
layout(barmode = 'stack')
