:: Many (probably most) charts leave some margin to left and right, allowing for a scale of possible values that is larger than the range of observed values. Perfectly resonable, and it doesn't require all 8 buckets to be equally full. |

:: Mathematica and R are graphing the data on the scale 0..8000. That's at least as reasonable as your approach (mathematically a little more simple and coherent too, as it happens), and it would be just as sensible (possibly even more) to follow their lead as yours. Both approaches are fine. |

::: The task is '''not''' to fill buckets evenly. The task is to produce a vertically proportional sparkline. Your test does not have a unique correct output.
