我想设置小提琴情节的最小界限,类似于这个问题:
set only lower bound of a limit for ggplot
为了这:
p <- ggplot(somedf, aes(factor(user1), pq)) + aes(ymin = -50)
p + geom_violin(aes(fill = user1))+ aes(ymin=-50)
我试过添加
+ expand_limits(y=-50)
和
+ aes(ymin = -50)
设置下限没有效果.
以下是导致相同问题的示例数据框:
structure(list(pq = c(-20L, -12L, 10L, -13L, 11L, -16L), time = c(1214.1333,
1214.1833, 1214.2667, 1214.2833, 1214.35, 1214.5167), pq.1 = c(-20L,
-12L, 10L, -13L, 11L, -16L), time.1 = c(1214.1333, 1214.1833,
1214.2667, 1214.2833, 1214.35, 1214.5167), time.2 = c(1214.1333,
1214.1833, 1214.2667, 1214.2833, 1214.35, 1214.5167), pq.2 = c(-20L,
-12L, 10L, -13L, 11L, -16L), user1 = structure(c(1L, 1L, 2L,
1L, 2L, 1L), .Label = c("someguy3", "someguy4", "someguy6", "someguy4",
"someguy5", "someguy6"), class = "factor"), pq.3 = c(-20L, -12L, 10L,
-13L, 11L, -16L), time.3 = c(1214.1333, 1214.1833, 1214.2667,
1214.2833, 1214.35, 1214.5167), user1.1 = structure(c(1L, 1L,
2L, 1L, 2L, 1L), .Label = c("someguy3", "someguy4", "someguy6",
"someguy4", "someguy5", "someguy6"), class = "factor")), .Names = c("pq",
"time", "pq.1", "time.1", "time.2", "pq.2", "user1", "pq.3",
"time.3", "user1.1"), row.names = c(565L, 566L, 568L, 569L, 570L,
574L), class = "data.frame")
最佳答案 如果你添加一个对geom_blank()的调用,ggplot会注意aes()指令.
## A reproducible example
library(ggplot2)
p <- ggplot(mtcars, aes(factor(cyl), mpg))
## This doesn't work:
p + aes(ymin = -10) + geom_violin()
## But this does:
p + aes(ymin = -10) + geom_violin() + geom_blank()
(注意:至少对于这个例子,expand_limits(y = -10)可以在有或没有伴随调用geom_blank()的情况下工作.)
