Bar growth direction — the histogram orientation. 'vertical' bars grow up
from a value baseline, bins on the x axis (the column / time-bucket look);
'horizontal' bars grow right, bins on the y axis (the band look, e.g.
heart-rate zones). The stacked geometry below transposes on this alone — the
StackedBarSeries data is identical for both.
