R ggplot2：时间序列的条形图 [英] R ggplot2: bar chart of a time series
本文介绍了R ggplot2：时间序列的条形图的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我有一份文件，显示过去十年股票的月度回报以及整个投资组合的总额。我想绘制这些变化，但我有两个问题。首先，R按日期按字母顺序对数据进行重新排序，而不是按日期的顺序排列（因为它们在文件中排序）。其次，日期轴太拥挤，我想每12个月只展示一个标签来清理它。我知道我的行标题实际上是字符而不是日期，但是当我尝试使用 as.Date（）函数来转换它们时，我遇到了一些其他奇怪的问题。 / p>
这是我的代码：
library（ggplot2）
库（比例）
wb红色<-rgb（红色= 187，绿色= 8，蓝色= 38，最大色彩值= 255）
样品< - read.csv（file =C：/Users/Desktop/sample.csv，header = TRUE，sep =，，row.names = 1）
ggplot（data = sample，aes （x = rownames（sample），y = Total））+ geom_bar（stat =identity，fill = bRed，color = wfRed）+
theme_bw（）+ theme（panel.border = element_blank（），panel .grid.major.x = element_blank（），
panel.grid.major.y = element_line（color =black），panel.grid.minor = element_blank（），axis.line = element_line（color = black））+
labs（x =，y =价值变化）+
#scale_x_date（breaks =12 months）+
ggtitle结果）+
指南（fill = FALSE）+
主题（axis.text.x = element_text（angle = 45，hjust = 1））

p> I have a file that shows the monthly returns on stocks as well as the total for the whole portfolio over the last ten years. I want to plot those changes but I am having two problems. First, R is reordering my data in 'alphabetical' order by date instead of the chronological order of the dates (as they are ordered in the file). Second, the date axis is too crowded, I would like to only show a label every twelve months to clean it up. I recognize that my row headers are actually characters and not dates but when I try to use the as.Date() function to convert them, I get some other weird issues.
Here is my code:
library(ggplot2)
library(scales)
wbRed <- rgb(red=187, green=8, blue=38, maxColorValue = 255)
sample<-read.csv(file="C:/Users/Desktop/sample.csv", header=TRUE, sep=",", row.names=1)
ggplot(data=sample, aes(x=rownames(sample), y=Total)) + geom_bar(stat="identity", fill=bRed, color=wfRed) +
theme_bw() + theme(panel.border = element_blank(), panel.grid.major.x = element_blank(),
panel.grid.major.y = element_line(colour = "black"), panel.grid.minor = element_blank(), axis.line = element_line(colour = "black")) +
labs(x="", y="Changes in Value") +
#scale_x_date(breaks="12 months") +
ggtitle("Historical Simulation Results") +
guides(fill=FALSE) +
theme(axis.text.x = element_text(angle = 45, hjust = 1))

You just have to format the dates you pass to x with as.Date, which requires a format so it knows how to parse them. Cleaned up a little bit:
library(ggplot2)
ggplot(data = sample, aes(x = as.Date(rownames(sample), "%m/%d/%Y"), y = Total)) +
geom_bar(stat = "identity",
position = 'dodge',
fill = rgb(187, 8, 38, maxColorValue = 255),
color = rgb(187, 8, 38, maxColorValue = 255)) +
theme_bw() +
theme(panel.border = element_blank(),
panel.grid.major.x = element_blank(),
panel.grid.major.y = element_line(colour = "black"),
panel.grid.minor = element_blank(),
axis.line = element_line(colour = "black"),
axis.text.x = element_text(angle = 45, hjust = 1)) +
labs(x = "", y = "Changes in Value", title = "Historical Simulation Results")
Format the axis with scale_x_date if you like.
