Plot multiple axis aligned with gnuplot

Question

I am trying to plot a time series on the left, and its histogram on the right. I have 10000 samples. The files ts.dat and hist.dat contains point to plot in the correct form. How can I plot the two axis aligned? With the code below, gnuplot aligns the canvas, and as the x labels are of different length the axis y length is different.

set term pngcairo font "Times New Roman, 8" size 640, 240
set out 'mp.png'
set multiplot
set tics out
set tics scale 0.5
unset key
set size .66, 1
set yrange[-6:6]
set xtics rotate by 45 right
set xlabel "Iteration no."
set ylabel "USD"
plot 'ts.dat' with lines
set origin .66, 0
set size .33, 1
set yrange [-6:6]
set format y ""
set style fill transparent solid 0.3
set xlabel "No. of occurences"
unset ylabel
plot 'hist.dat' using 2:1 with filledcurves
unset multiplot

What exactly do you want to be different in that image? The y axes look aligned to me, thanks to the matching set yrange [-6:6] calls. — NicholasM

the x axis on the right chart is below the x asis on the left chart since the y-axis on the right chart is slightly longer than the correspondant y-axis on the left. — Eamon

Okay, I see it now. The mis-alignment is pretty small in the image and I simply missed it upon first glance. — NicholasM

Check help margins.

If you set a fixed bottom margin manually, e.g. set bmargin 3 or set bmargin at screen 0.1, the bottom x-axes should be aligned in both plots.
