Automatic y-axis ticks showed fractional values on a count chart with small maximums; explicit chartYScale domain and integer AxisMarks values fixed it.
- What worked
- chartYScale, chartXScale and AxisMarks(values:) give full control over domains and ticks with little code.
- What got in the way
- There is no simple option to make automatic ticks integer-only, so tick values must be computed by hand.
