R ggplot 按日期分组并从同一日期时间在 x 轴上绘制时间
R ggplot group by date and plot time in the x axis from the same datetime
我有一个 df 和一个整型变量 counts 和一个 POSIXct datetime 变量。 datetime 变量表示不同日期的分钟间隔：
counts datetime
246 02/11/2011 19:00
237 02/11/2011 19:01
268 02/11/2011 19:02
496 02/11/2011 19:03
259 02/11/2011 19:04
548 09/12/2011 20:14
我想为每一天画一个线图，x 轴上有不同的 HH:MM。我可以通过 lubridate:
获取日期、小时和分钟
require(lubridate)
day(df$datetime)
minute(df$datetime)
但我无法将它们放在一起（我试过将 datetime 转换为 HH:MM 字符的方法未成功）。我缺少下面的 "x=factor(HH:MM of datetime)"。有什么想法评论吗？
ggplot(df, aes(x=factor(HH:MM of datetime), y=counts, group=day(datetime)) + geom_line()
示例：每行应该是不同的一天。 x 轴应该是 HH:MM，y 轴是计数。

你可以试试
library(ggplot2)
library(scales)
df$date <- factor(as.Date(df$datetime))
df$dtime <- as.POSIXct(sprintf('%s %s:%s', Sys.Date(),
format(df$datetime, '%H:%M'), '00'))
p <- ggplot(df, aes(x=dtime, y=all, group=date, color=date))+
geom_line()
p+
scale_x_datetime(breaks=date_breaks('1 hour'),
labels=date_format('%H:%M')) +
theme_light()
我有一个 df 和一个整型变量 counts 和一个 POSIXct datetime 变量。 datetime 变量表示不同日期的分钟间隔：
counts datetime
246 02/11/2011 19:00
237 02/11/2011 19:01
268 02/11/2011 19:02
496 02/11/2011 19:03
259 02/11/2011 19:04
548 09/12/2011 20:14
我想为每一天画一个线图，x 轴上有不同的 HH:MM。我可以通过 lubridate:
require(lubridate)
day(df$datetime)
minute(df$datetime)
但我无法将它们放在一起（我试过将 datetime 转换为 HH:MM 字符的方法未成功）。我缺少下面的 "x=factor(HH:MM of datetime)"。有什么想法评论吗？
ggplot(df, aes(x=factor(HH:MM of datetime), y=counts, group=day(datetime)) + geom_line()
示例：每行应该是不同的一天。 x 轴应该是 HH:MM，y 轴是计数。
