The y-axis ticks and the hover both carry the unit now — an axis in euros with a
bare number in the tooltip reads as two different quantities.
Two formatters, not one: the axis rounds to whole euros to keep the labels short,
but the tooltip keeps the cents. Rounding an amount someone is reading off a
chart to answer "how much did we take in March" is a lie, and €1.234,50 becoming
"€ 1.235" is exactly that.
Locale is nl-BE, so it renders "€ 1.234,50" rather than "€1,234.5".
