In recent versions of Gnuplot, the dumb terminal refuses to print the y-axis label, despite apparently making enough room for it.
Example:
gnuplot> set terminal dumb 80 35
Terminal type is now 'dumb'
Options are 'feed size 80, 35 aspect 2, 1 mono'
gnuplot> set title 'Test title'
gnuplot> set xlabel 'Test xlabel'
gnuplot> set ylabel 'test ylabel'
gnuplot> plot '-' using 1:2 title '' with lines
input data ('e' ends) > 1 200
input data ('e' ends) > 2 400
input data ('e' ends) > 3 300
input data ('e' ends) > 4 600
input data ('e' ends) > e

Test xlabel
No y-axis label, and yet
gnuplot> show ylabel
ylabel is "test ylabel", offset at (character 0, 0, 0), rotated by -270 degrees in 2D plots textcolor lt -1
Interestingly, it seems that the space to the left of the y-axis is made to measure to the length of the y-axis label, it's just that the label itself never gets printed:

Let's break it down, what happens with one character?
Aha, we have a label but it looks as though the spacing is dodgy. Let's try setting an offset.
Much better. Does this always work?
Clearly not. Let's try a bigger offset.
OK, so it's clear that we need a horizontal offset equal to
len(xlabel) // 2.
