ggplot2使用单独的日期和可变日期框架按日期绘制时间序列 [英] ggplot2 to plot time series by date using seperate date and variable dateframes r
问题描述
我正在尝试绘制时间序列.在一个数据帧(y)中，我在列向量中有56个项目，在第二个数据帧(日期)中有相应的日期.我正在尝试将时间序列绘制为y轴上的y值和x轴上的日期.我已经尝试过使用ggplt2 geom_freqpoly进行许多操作，但是我无法弄清楚.我对ggplot以外的其他方法持开放态度，如果可以使事情变得更容易，我也可以将date和y绑定到一个dateframe中.
I'm trying to plot a time series. In one dataframe(y), I have 56 items in a column vector and I have a second dataframe (dates) with corresponding dates. I am trying to graph the time series as the values of y on the y-axis and the dates on the x axis. I have tried a number of things using ggplt2 geom_freqpoly but I can't figure it out. I'm open to other methods besides ggplot and i can cbind date and y into one dateframe as well if it will make things easier.
有什么建议吗?
library(ggplot2)
set.seed(123)
N<- 500
M<-56
x<- matrix( rnorm(N*M,mean=23,sd=3), N, M)
y <- colMeans(x,dim=1)
y <-as.data.frame(y)
Date <- seq(as.Date("2018-01-01"), as.Date("2018-02-25"), by="days")
Date <- as.POSIXct(Date, format = "%Y-%m-%d %H:%M")
a <- ggplot(date, aes(y))
a + geom_freqpoly()
推荐答案
以下是来自多个不同程序包的方法.
Here are methods from several different packages.
ggplot2
ggplot2 软件包在数据框，所以我建议您使用数据创建一个数据框.另外，不确定为什么要使用geom_freqpoly.我认为geom_line将适用于时间序列数据.
The ggplot2 package works the best on a data frame, so I would suggest you to create a data frame with your data. In addition, not sure why do you want to use geom_freqpoly. I think geom_line will work for time-series data.
library(ggplot2)
set.seed(123)
N<- 500
M<-56
x<- matrix( rnorm(N*M,mean=23,sd=3), N, M)
y <- colMeans(x,dim=1)
Date <- seq(as.Date("2018-01-01"), as.Date("2018-02-25"), by="days")
Date <- as.POSIXct(Date, format = "%Y-%m-%d %H:%M")
dat <- data.frame(Date = Date, y = y)
ggplot(dat, aes(x = Date, y = y)) +
geom_line() +
theme_classic()
ggpubr
ggpubr 是ggline包来绘制数据.
ggpubr is an extension of the ggplot2 package. We can use ggline package to plot the data.
library(ggpubr)
ggline(data = dat, x = "Date", y = "y")
晶格
我们还可以使用 lattice的问题中的xyplot函数包.
We can also use the xyplot function from the lattice package.
library(lattice)
xyplot(y ~ Date, data = dat, type = "l")
ggvis
ggvis 软件包的问题，类似于 ggplot 的问题，使用图形语法创建绘图.
The ggvis package, similar to ggplot, uses grammar of graphics to create plots.
library(ggvis)
ggvis(dat, ~Date, ~y) %>% layer_lines()
基本R
我们也可以使用底数R.
We can also use the base R.
plot(dat$Date, dat$y, xaxt = "n", type = "l", xlab = "Date", ylab = "y")
axis.POSIXct(1, at = seq(min(dat$Date), max(dat$Date), by = "week"), format="%b %d")
xts
我们还可以将数据框转换为xts 对象，然后将其绘制.
We can also convert the data frame to an xts object and then plot it.
library(xts)
dat.ts <- xts(dat$y, order.by = dat$Date)
plot(dat.ts)
PerformanceAnalytics
我们还可以使用performanceanalytics 包以绘制xts包.
We can also use the chart.TimeSeries from the performanceanalytics package to plot the xts package.
chart.TimeSeries(dat.ts)
图表
dygraphs 包可以创建交互式时间，系列图.
The dygraphs package can create interactive time-series plot.
library(dygraphs)
dygraph(dat.ts)
密谋
我们还可以使用plotly 情节.
library(plotly)
plot_ly(x = ~dat$Date, y = ~dat$y, mode = 'lines')
我们还可以使用 highcharter 包来创建互动情节.
We can also use highcharter package to create interactive plot.
library(highcharter)
hchart(dat.ts)
