The ‘print-Y-axis’ Function in Detail
-------------------------------------
It is easy enough to see in the figure what the Y axis label should look
like; but to say in words, and then to write a function definition to do
the job is another matter. It is not quite true to say that we want a
number and a tic every five lines: there are only three lines between
the ‘1’ and the ‘5’ (lines 2, 3, and 4), but four lines between the ‘5’
and the ‘10’ (lines 6, 7, 8, and 9). It is better to say that we want a
number and a tic mark on the base line (number 1) and then that we want
a number and a tic on the fifth line from the bottom and on every line
that is a multiple of five.
