r - 在 R 中垂直堆叠多个图，具有相同的 x 轴但不同的 Y 轴

Question

我有一个 data.frame，其中包含针对日期:时间向量的多个时间序列向量。我想绘制所有相关向量，垂直堆叠在具有相同 X 轴但唯一 Y 轴的单独图表上。类似于此的图表:

我的数据如下所示:

 dt <- structure(list(DEPTH = c(156, 156.5, 157.4, 158.15, 158.8, 159.2,

我希望在具有公共(public) X 轴的单独图表上绘制深度、X、Y 和 Z。

Answer 1

我同意@PaulHiemstra，ggplot2 是正确的选择。

假设 Smooth.Vert.Speed 是您要绘制 DEPTH、X、 的常用 x 轴变量Y 和 Z...

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")
