当我运行代码时，它在时间范围内给出直的垂直线而不是连续的水平线

p<-ggplot(Trafic.df2, aes(x=TIME, y=Count1, group=vehicle)) +
geom_line(aes(color=vehicle))

p

我希望图表看起来像这样：

r

你应该提到colour和group美学中的vehicle来创建多个连续的线条。我创建了一个可复制的示例数据：

Trafic.df2 <- data.frame(vehicle = c("PCL", "MCL", "CAR", "TAXI", "LGV", "OGV1", "OGV2", "CDB", "BEB", "OB", "PCL", "MCL", "CAR", "TAXI", "LGV", "OGV1", "OGV2", "CDB", "BEB", "OB", "PCL", "MCL", "CAR", "TAXI", "LGV", "OGV1", "OGV2", "CDB", "BEB", "OB"),
                 Count1 = runif(30, 0, 5),
                 TIME1 = c("07:00:00", "07:00:00", "07:00:00", "07:00:00", "07:00:00", "07:00:00", "07:00:00", "07:00:00", "07:00:00", "07:00:00", "07:15:00", "07:15:00", "07:15:00", "07:15:00", "07:15:00", "07:15:00", "07:15:00", "07:15:00", "07:15:00", "07:15:00", "07:30:00", "07:30:00", "07:30:00", "07:30:00", "07:30:00", "07:30:00", "07:30:00", "07:30:00", "07:30:00", "07:30:00"))

   vehicle     Count1    TIME1

您可以使用以下代码：

library(tidyverse)

Trafic.df2 %>%
  ggplot(aes(x = TIME1, y = Count1, colour = vehicle, group = vehicle)) +
  geom_line() +
  xlab("time") +
  ylab("count") +
  theme_minimal()

输出如下所示：

行不长，因为我只创建了三个不同时间点的数据。
