In 7.6.4, when using setDataTextPosition(5) on a stacked bar graph, I end up with the data text labels overlapping each other. I'd like them to appear at the bottom of each portion / segment of the stacked bar

Have you played with the number in here?
setDataTextPosition(5);
You can get it to un-overlap.
