--DOC_HIDE These are not useful examples, but rather a gathering of fringe cases
--DOC_HIDE that should provide code coverage to ensure that we're handling them.

--DOC_HIDE Tests behavior of autoscaling when graph contains only equal values.
--DOC_HIDE This widget will also be rendered multiple times with different
--DOC_HIDE sizes, to test last_drawn_values_num stats gathering.
