method.
It is a subclass of C<Chart::OFC::Dataset> and accepts all of that
class's attributes as well as its own.
=head2 opacity
This defines how opaque the bars are. When they are moused over, they
become fully opaque.
Defaults to 80 (percent).
=head2 fill_color
The color used to fill the bars.
Defaults to #999999 (medium grey).
=head2 label
If provided, this will be shown as part of the chart key. The label
will be the same color as the fill_color for the bars.
This attribute is optional.
=head2 text_size
This is the size of the text in the key.
Defaults to 10 (pixels).
=head1 ROLES
This class does the C<Chart::OFC::Role::OFCDataLines> role.
