我正在做一个项目,需要使用ggplot2来绘制时间序列数据.这是我使用的数据集:
这就是我现在所做的:
library(ggplot2)
library(lubridate)
eur$Date <- as.Date(eur$Date)
ggplot(eur, aes(Date, EUR)) + geom_line()
我得到了这个非常奇怪的情节.有人可以帮我解决问题吗?
编辑 – 如果您的数据属于班级时间序列(ts),那么您可以使用ggfortify的自动抽样功能,它将为您完成转换.
library(ggfortify)
library (ggplot2)
ggfortify::autoplot(df)
如果您的数据不是时间序列,则您的日期列可能是因子或字符.
如果是as.Date(foo)的字符转换
如果它是一个因素,请参阅下文
#create the data
data <- data.frame(
i = c(6L, 7L, 8L, 9L, 10L, 11L, 12L, 13L, 14L, 15L, 16L, 17L),
Date = c("2000-01-03", "2000-01-04", "2000-01-05", "2000-01-06",
"2000-01-07", "2000-01-10", "2000-01-11", "2000-01-12",
"2000-01-13", "2000-01-14", "2000-01-18", "2000-01-19"),
EUR = c(1.0155, 1.0309, 1.0335, 1.0324, 1.0294, 1.0252, 1.0322,
1.0281, 1.027, 1.0128, 1.0121, 1.0115)
)
#check the data
str(data)
# convert date column to Date as it is currently a **factor**
data$Date <- as.Date(as.character(data$Date))
#basic plot
library(ggplot2)
ggplot(data,aes(Date, EUR)) + geom_line() + geom_point()
## plot can be tidied up further using lubridate/scales packages
