I think that I've found the solution (haven't yet tested it, though):
<https://statisticsglobe.com/combine-two-ggplot2-plots-from-different-data-frames-in-r>.

It's from Statistical Globe and uses this code:
ggp <- ggplot(NULL, aes(x, y)) +    # Draw ggplot2 plot based on two data frames
   geom_point(data = data1, col = "red") +
   geom_line(data = data2, col = "blue")
ggp                                 # Draw plot

More when I try it with four boxplots.
