[英]Stacking multiple plots, vertically with the same x axis but different Y axes in R
我有一個帶有多個時間序列向量的 data.frame 與 date:time 向量。 我想繪制所有相關向量,垂直堆疊在具有相同 X 軸但唯一 Y 軸的單獨圖表上。 與此類似的圖表:
我的數據如下所示:

我希望在具有共同 X 軸的單獨圖表上繪制 DEPTH、X、Y 和 Z。
我同意@PaulHiemstra,ggplot2是要走的路。
假設Smooth.Vert.Speed
是您想要繪制DEPTH
, X
, Y
和Z
的常見x軸變量...
library(ggplot2)
library(reshape2)
# Add time variable as per @BenBolker's suggestion
dt$time <- seq(nrow(dt))
# Use melt to reshape data so values and variables are in separate columns
dt.df <- melt(dt, measure.vars = c("DEPTH", "X", "Y", "Z"))
ggplot(dt.df, aes(x = time, y = value)) +
geom_line(aes(color = variable)) +
facet_grid(variable ~ ., scales = "free_y") +
# Suppress the legend since color isn't actually providing any information
opts(legend.position = "none")
如果你想要老式,你可以使用lattice
。 與@aaronwolen不同,我假設數據集中有一個缺少的time
變量,所以我做了一個:
dt$time <- seq(nrow(dt))
library(reshape2)
mm <- melt(subset(dt,select=c(time,DEPTH,X,Y,Z)),id.var="time")
library(lattice)
xyplot(value~time|variable,data=mm,type="l",
scales=list(y=list(relation="free")),
layout=c(1,4))
我實際上已經找到了另一個有趣的方法,使用動物園庫:
library(zoo)
z <- with(dt, zoo(cbind(DEPTH, X, Y, Z),as.POSIXct(time)))
plot.zoo(z, ylab=c("Depth (m)", "Pitch Angle (degrees)", "Swaying Acceleration (m/s^2)", "Heaving Acceleration (m/s^2)"), col=c("black", "blue", "darkred", "darkgreen"),
xlab = c("Time"), lwd=2, ylim=list((rev(range(dt$DEPTH))), c(-90,90), c(-10,10), c(-10,10)))
因此,在動物園圖中,您可以創建新的軸標簽作為列表形式,並且所有圖可以具有不同的顏色。
請閱讀這個例子:
