The title
and subtitle
commands can be used to specify titles
for the chart. You must supply a label, perhaps using the colon syntax.
title: This is a title; subtitle: This is a subtitle;
The title and subtitle include text and a box around the text - the latter
being omitted in the ‘plain’ design. You can turn it on by setting
the ‘line.*’ and ‘fill.*’ attributes.
The default attributes are taken from the default styles title
and
subtitle
, changing these will affect all titles in the chart.
Entity lines are not drawn behind the titles by default, this can be changed
by setting the vline.*
attribute.
