The race track chart was the topic of Jon Peltier's Chart Busters on June 25. Here's the link: http://peltiertech.com/WordPress/chart-busters-calorie-chart/

The bar should still start at zero. It's just that the quoted number should be the relevant metric, which is the over-age of males relative to females.

The iron rule is that bars should be rectangles of visible length proportional to the number being depicted. If the graph doesn't show the whole bar, or shows a bar longer than the relevant metric, then the the graph is wrong.

This goes for floating bars too. In fact, the concept can be neatly regularized by defining a vanilla bar graph as a "floating" bar graph whose bars happen to float on the base line. You wouldn't conceal parts of a floating bar, or stretch a floating bar down to the bottom of the graph, so why do it to a regular bar?
