问题描述
情况&数据
我有一个比赛中运动员位置的数据框df
(我已经melted
它与ggplot2
一起使用):>
df <- structure(list(athlete = c("A", "B", "C", "D", "E", "F", "G",H"、I"、J"、A"、B"、C"、D"、E"、F"、G"、H"、I"、J"",A"、B"、C"、D"、E"、F"、G"、H"、I"、J"、A"、B"、C"",D"、E"、F"、G"、H"、I"、J"、A"、B"、C"、D"、E"、F"",G"、H"、I"、J"、A"、B"、C"、D"、E"、F"、G"、H"、I"","J"), distanceRemaining = 结构(c(1L, 1L, 1L, 1L, 1L, 1L,1L, 1L, 1L, 1L, 2L, 2L, 2L, 2L, 2L, 2L, 2L, 2L, 2L, 2L, 3L, 3L,3L, 3L, 3L, 3L, 3L, 3L, 3L, 3L, 4L, 4L, 4L, 4L, 4L, 4L, 4L, 4L,4L, 4L, 5L, 5L, 5L, 5L, 5L, 5L, 5L, 5L, 5L, 5L, 6L, 6L, 6L, 6L,6L, 6L, 6L, 6L, 6L, 6L), .Label = c("1400m", "1200m", "600m","400m", "200m", "FINISH"), class = "factor"), position = c(10,6, 7, 8, 2, 1, 3, 5, 9, 4, 9, 8, 7, 6, 4, 3, 1, 5, 10, 2, 8,7, 9, 5, 6, 2, 3, 1, 10, 4, 9, 8, 6, 5, 7, 3, 2, 4, 10, 1, 4,5, 1, 6, 8, 3, 2, 7, 10, 9, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10)), row.names = c(NA,-60L), .Names = c("athlete", "distanceRemaining", "position"), class = "data.frame")
我正在绘制数据
库(ggplot2)g <- ggplot(df, aes(x=distanceRemaining, y =position, colour=athlete, group = athlete))g <- g + geom_point()g <- g + geom_line(size=1.15)g <- g + scale_y_discrete()G

如何颠倒 y 轴的顺序,使 10 在底部,1 在顶部?

Situation & data
I have a dataframe df
of athlete positions in a race (I've already melted
it for use with ggplot2
):
df <- structure(list(athlete = c("A", "B", "C", "D", "E", "F", "G",
"H", "I", "J", "A", "B", "C", "D", "E", "F", "G", "H", "I", "J",
"A", "B", "C", "D", "E", "F", "G", "H", "I", "J", "A", "B", "C",
"D", "E", "F", "G", "H", "I", "J", "A", "B", "C", "D", "E", "F",
"G", "H", "I", "J", "A", "B", "C", "D", "E", "F", "G", "H", "I",
"J"), distanceRemaining = structure(c(1L, 1L, 1L, 1L, 1L, 1L,
1L, 1L, 1L, 1L, 2L, 2L, 2L, 2L, 2L, 2L, 2L, 2L, 2L, 2L, 3L, 3L,
3L, 3L, 3L, 3L, 3L, 3L, 3L, 3L, 4L, 4L, 4L, 4L, 4L, 4L, 4L, 4L,
4L, 4L, 5L, 5L, 5L, 5L, 5L, 5L, 5L, 5L, 5L, 5L, 6L, 6L, 6L, 6L,
6L, 6L, 6L, 6L, 6L, 6L), .Label = c("1400m", "1200m", "600m",
"400m", "200m", "FINISH"), class = "factor"), position = c(10,
6, 7, 8, 2, 1, 3, 5, 9, 4, 9, 8, 7, 6, 4, 3, 1, 5, 10, 2, 8,
7, 9, 5, 6, 2, 3, 1, 10, 4, 9, 8, 6, 5, 7, 3, 2, 4, 10, 1, 4,
5, 1, 6, 8, 3, 2, 7, 10, 9, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10)), row.names = c(NA,
-60L), .Names = c("athlete", "distanceRemaining", "position"), class = "data.frame")
I'm plotting the data with
library(ggplot2)
g <- ggplot(df, aes(x=distanceRemaining, y =position, colour=athlete, group = athlete))
g <- g + geom_point()
g <- g + geom_line(size=1.15)
g <- g + scale_y_discrete()
g
To give
Question
How do I reverse the order of the y-axis so that 10 is at the bottom and 1 is at the top?
解决方案
There is a new solution, scale_*_discrete(limits=rev)
, example:
tibble(x=1:26,y=letters) %>%
ggplot(aes(x,y)) +
geom_point() +
scale_y_discrete(limits=rev)
