Figure 3-24. Labels on stacked bars
When using labels, changes to the stacking order are best done by modifying the order of levels
in the factor (see
Changing the Order of Factor Levels
)
before taking the cumulative sum. The
other method of changing stacking order, by specifying
breaks
in a scale, won't work properly,
because the order of the cumulative sum won't be the same as the stacking order.
