根据我的数据(如下图所示)称为GDP。我希望知道如何在一张图中绘制所有国家的数据,并且希望每个国家都有一个图例,例如每条线用不同的颜色或形状表示。
我知道如何绘制单个系列的图表,例如:
ts.plot(GDP$ALB)
但不知道如何绘制所有系列并包含图例。
谢谢。

使用 ts.plot 仅需 2 行代码
ts.plot(time,gpars= list(col=rainbow(10)))
legend("topleft", legend = 1:10, col = 1:10, lty = 1)
结果:如何在R中使用图例绘制多个(时间)序列
xts
创建时间序列数据,您可以使用来自xtsExtra
包的plot.xts
来获得所需的结果。#Uncomment below lines to install required packages

plot.xts(data, screens = factor(1, 1), auto.legend = TRUE)
plot.xts(data, auto.legend = TRUE)
install.packages("xtsExtra", repos="http://R-Forge.R-project.org")
或者只是 install.packages("xtsExtra")
吗? - CHPplot.ts
一件事就是不显示 x 轴标签作为日期。此外,现在已经没有 auto.legend = TRUE
选项了。取而代之的是:legend.loc = 'topleft'

现在,这里有两个基本的绘图选项:
# Each country in a separate panel, no legends required
plot(DF.TS)
# All countries in one plot... colorful, common scale, and so on
plot(DF.TS, plot.type="single", col = 1:ncol(DF.TS))
legend("bottomleft", colnames(DF.TS), col=1:ncol(DF), lty=1, cex=.65)
