Basically my data looks something like this,
Year, group1, group2, group3
1999, 500, 1200, 1700
2000, 700, 3000, 2000
2001, 500, 4500, 2500
I want to have a stacked geom_area chart. If possible, without the use of libraries outside of dplyr
An example of the desired output:
CodePudding user response:
We can do it all within the tidyverse. Use tidyr::pivot_longer
to get the data in the right format, with a value variable and a grouping variable(here "name"). Use ggplot with the fill
aesthetic mapped to the grouping variable.
library(dplyr)
library(ggplot2)
library(tidyr)
df %>% pivot_longer(!Year)%>%
ggplot(aes(x=Year, y=value, fill=name))
geom_area()
