[英]How can I make a stacked area chart?
我正在嘗試制作堆積區域圖表:
library(ggplot2)
ggplot(data, aes(x = variable, y = value, fill = term)) +
geom_area()
但這導致了一個空白的情節。
預期的情節(例子)
我怎樣才能做到這一點?
data <- structure(list(term = c("models", "percentiles", "models:percentiles",
"models", "percentiles", "models:percentiles",
"models", "percentiles", "models:percentiles"),
variable = structure(c(1L, 1L, 1L, 2L, 2L, 2L, 3L, 3L, 3L),
.Label = c("R2", "R5", "R10"), class = "factor"),
value = c(0.435697205847009, 0.533615307749147, 0.0306874864038442,
0.441369621882273, 0.520198994695284, 0.0384313834224421,
0.394491546635206, 0.579421546902868, 0.0260869064619254)),
row.names = c(NA, -9L), class = "data.frame")
