### 9.1 Titles ¶

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.
