Bins of ten
The histogram of e-bike batteries has 11 bars and the last one is 100-110, although no battery is above 100.
Use the fixed range 0 to 100 and ten bins, so the page shows 10 bars and the last one holds 23 bikes.
What Check tests
- The chart has 10 bars
- The last bar counts 23 bikes
- No attribute holds NaN
