I'm trying to create a multiple plot with the same x-axis but different y-axes, because I have values for two groups with different ranges. As I want to control the values of the axes (respectively the y-axes shall reach from 2.000.000 to 4.000.000 and from 250.000 to 500.000), I don't get along with facet_grid with scales = "free".
So what I've tried is to create two plots (named "plots.treat" and "plot.control") and combine them with grid.arrange and arrangeGrob. My problem is, that I don't know how to control the exact position of the two plots, so that both y-axes are positioned on one vertical line. So in the example below the second plot's y-axis needs to be positioned a bit more to the right.
Here is the code:

Do:
install.packages("cowplot")
but do not library(cowplot) as it'll mess up your theme work.
Then, do:
grid.arrange(
arrangeGrob(cowplot::plot_grid(plot.treat, plot.control, align = "v", ncol=1),
ncol = 1,
left = textGrob("Aggregierte Depositen (in Tausend US$)",
rot = 90,
vjust = 1,
gp = gpar(fontfamily = "Times",
size = 12,
colout = "black",
fontface = "bold")),
bottom = textGrob("Jahr",
vjust = 0.1,
hjust = 0.2,
gp = gpar(fontfamily = "Times",
size = 12,
colout = "black",
fontface = "bold"))))
