You can either modify the axis labels of subplots
p = plot(
rand(100, 4),
layout = 4,
label = ["a" "b" "c" "d"],
title = ["1" "2" "3" "4"],
)
xlabel!(p[3], "hi")
xlabel!(p[4], "hi")
ylabel!(p[1], "bye")
ylabel!(p[3], "bye")
or specify them for each subplot in the plot command by passing row vectors.
p = plot(
rand(100, 4),
layout = 4,
label = ["a" "b" "c" "d"],
title = ["1" "2" "3" "4"],
xlabel = ["" "" "hi" "hi"],
ylabel = ["bye" "" "bye" ""],
)
Both result in this plot:
