Divide plot into boxes

There are probably more elegant approachers, but this should get you started. You will need to replace the random values with your own values.

using Plots, Random 
Random.seed!(5474)

n_lines = 2
min_x = 0
max_x = 10
min_y = 0
max_y = 10
mid_point = (2 + n_lines) / 2 + 1
padding = 1

xvals = range(min_x, max_x, length = n_lines + 2)
yvals = range(min_y, max_y, length = n_lines + 2)

p = plot(framestyle=:box, grid=false, 
    xlims=(min_x,max_x), ylims=(min_y,max_y))
for r in 2:length(xvals), c in 2:length(yvals)
    rnd_x = rand(5) * (xvals[c] .- xvals[c-1] .- 2 * padding) .+ xvals[c-1] .+ padding
    rnd_y = rand(5) * (yvals[r] .- yvals[r-1] .- 2 * padding) .+ yvals[r-1] .+ padding
    color = (r == mid_point) && (c == mid_point) ? :black : :red
    scatter!(rnd_x, rnd_y, leg=false, markerstrokecolor=color, 
        markercolor=:white, markerstrokewidth=4)
    c ≠ length(xvals) ? hline!([xvals[c]], color=:red) : nothing
    r ≠ length(xvals) ? vline!([yvals[r]], color=:red) : nothing
end
display(p)
