The bars were set to the z-value of the labels. Not an issue,
since the labels are generated after the bars and therefore
plot later. Still, do the right thing.

Implement a bar series, which can plot stacked, grouped and single
bar charts in horizontal or vertical ways. On hovering over a
bar, an information is shown. The shown information depends on
whether the chart is count or value based, or is a multi-bin
chart.
