PyPlot.jl reduce white space after tight_layout()

Can I reduce the amount of whitespace between subplots after the plot?

Please note I need AA and BB to have linked X, Y axes and the same sizes with a shared colorbar, and that AA, BB and CC need to have a shared X axis.

Here’s the MWE

fig, ax = plt.subplots(4, 1, gridspec_kw=Dict("height_ratios" => [1,4,4,1]),
        figsize=(10,5))
ax[1].plot(rand(10))
ax[1].set_title("CC")
ax[2].imshow(rand(10,10), aspect="auto")        
ax[2].sharex(ax[1])
ax[2].set_title("BB")
imlast = ax[3].imshow(rand(10,10), aspect="auto")
ax[3].set_title("AA")
ax[3].set_xlabel("AA xlabel")
ax[3].sharex(ax[2])
map(x->x.tick_params(labelbottom=false), ax[1:end-2])
fig.colorbar(imlast, cax=ax[4], orientation="horizontal", label="Log₁₀ S/m")
fig.tight_layout()

The number of rows can vary, and sharex in the initial subplots() invocation above isn’t appropriate because of the cax=ax[4]

Take a look at constrained_layout guide with padding and spacing. I hope, it will help.

Thanks, turns out that tigh_layout() even without constrained layout, can take an h_pad argument which can reduce the minimum space.
