<p>Labels are placed below the graph. When they overflow to the left, they wrap
to the next line. By default, lines are justified left and right. The
<strong>TEXTALIGN</strong> function lets you change this default. This is a command and
not an option, so that you can change the default several times in your
argument list.</p>

<p><strong>Some notes on stacking</strong></p>
<p>When stacking, an element is not placed above the X-axis but rather
on top of the previous element. There must be something to stack

example showing how to use centered formatting.</p>

<p>Normally there are two space characters inserted between every two items
printed into the graph. The space following a string can be suppressed by
putting a <strong>\g</strong> at the end of the string. The <strong>\g</strong> also ignores any space
