I’m looking to sort a stacked graph as demonstrated here: How to plot multiple stacked histograms together in R?
However I need the x axis not to be ‘value’ with numbers, but instead have groups like ‘car’ ‘van’ ‘bike’, with the stacked plots occuring for each group. I’m not great at R yet and I can’t work out how to edit it to do what I need. Explanations to solutions so I can learn and improve would also be really appreciated. Thanks
example input:
Output plot would have ‘car’, ‘van’, ‘bike’ on the x axis, ‘count’ on y axis, the stack on each group being made up of the ‘red’, ‘blue’, ‘yellow’ counts
I think I may have found the answer here:https://r-charts.com/part-whole/stacked-bar-graph/
If no ones solves it before I’ve had a go at the above link I may sort an answer myself, will see how things go.
>Solution :
Assuming that the last row of your dataset actually refers to the name of the column, you may need to lengthen your data.
library(tidyverse)
df <- data.frame(
"color" = c("red", "blue", "yellow"),
"car" = c(6,2,2),
"van" = c(1,4,4),
"bike" = c(8,1,1)) %>%
pivot_longer(cols = -color,
names_to = "name",
values_to = "value")
ggplot(df, aes(x = name, y = value, fill = color)) +
geom_bar(position = "stack", stat = "identity")
