我花了几个小时在stackoverflow.com上搜索重新排序分组条形图,但没有找到我想要的答案。我想更改条形图和图例的顺序,以按该顺序打印“之前”、“期间”和“之后”,但R一直按字母顺序打印因子,如“之后”、“之前”和“期间”,不知道如何修复。
如果有人能帮助我,我将心存感激!
这是我想更改的R显示顺序。
这是我的代码:
df <- data.frame(time = c("after","before","during","before","after","before","during","after","after","during", "during","after","before","during","before"),
variable = c("granny", "red del", "other", "golden", "star", "granny", "red del", "other", "golden", "star", "granny", "red del", "other", "golden", "star"),
value = c(34,66,7,12,99,35,66,82,55,48, 27,55,82,42,26))
df$time = as.factor(df$time)
df$variable = as.factor(df$variable)
ggplot(df, aes(x = variable, y = value, fill = time)) +
geom_bar(position='dodge', stat='identity') +
theme_minimal() +
labs(x=' ', y=' ', title=' ') +
theme(plot.title = element_text(hjust=0.5, size=20, face='bold')) +
theme_bw() +
theme(axis.line = element_line(color='black'),
plot.background = element_blank(),
panel.grid.minor = element_blank(),
panel.grid.major = element_blank())
