Target: Plot an image like this: Features: 1. two different time series; 2. the lower panel has a reverse y-axis; 3. shadows over two plots. Possible solutions: 1. Facetting is not appropriate - (1) can not just make one facet's y axis reverse while keep the other(s) unchanges. (2) difficult to adjust the individual facets one by one. 2. Using viewports to arrange individual plots using the following codes: library(ggplot2) library(grid) library(gridExtra) ##Import data df<- read.csv("D:\\R\\SF_Question.csv") #
