All bars now share one baseline, because each column has a label row
of the same height. Before, only columns with a day number had a label
row, so their bars sat higher.
Only the peak bar has a value label, so labels no longer overlap in a
31-day month. A readout line above the chart shows the date and value
of the bar that the user hovers, taps or focuses.
Day numbers are no longer cut, a period with no time has no bar, the
axis line sits at the bar baseline, and bars are 24px wide or less.
