I'm currently a beginner in Plotly and have a problem I can't seem to solve. I have my plotly stacked bar chart but I don't know how to color each individual category. I am currently using R.
This is my current stacked bar chart:
My current code is:
p = plot_ly(x, x = day, y = count, type = "bar", group = status) %>% layout(barmode = "stack", showlegend = T)
"color = "
You need to specify a factor for the
color parameters, and then a vector of colours for the
Here is a simple solution. Note the ordering required on the data frame before plotting.
require(dplyr) require(plotly) set.seed(42) df <- data.frame(x = rep(LETTERS[1:5], 3), y = rexp(15, rate = 0.5), z = c(rep("Adam", 5), rep("Arthur", 5), rep("Ford", 5))) df <- arrange(df, desc(z)) plot_ly(df, x = x, y = y, color = z, colors = c("grey50", "blue", "red"), type = "bar") %>% layout(barmode = "stack")
The ordering on the data frame matters strangely. I would have thought
plot_ly would use the order of the levels but it doesn't.
This example uses
plotly 3.x.x. If you use
plotly 4.x.x or above, this code may not work as is. See here for more details: https://www.r-bloggers.com/upgrading-to-plotly-4-0-and-above/
