Box plots with log-scaled whiskers

The standard formula we use for the length of box plot whiskers is 1.5 * IQR (interquartile range, ie the third quartile minus the first quartile). This is based on comparing your distribution to a normal distribution, where any data beyond those whiskers is considered an outlier. However, if you're displaying your data on a log scale (and sometimes even if you're not) a log-normal distribution is likely more appropriate, in which case the whisker locations should be calculated based on the IQR in log units. This brings both fences up, in particular preventing the lower fence from ever going negative ie an infinitely long whisker on a log scale.

I'd propose a new attribute for box traces, something like distribution: 'normal' | 'log-normal' | 'auto' where 'auto' uses 'log-normal' when displayed on a log axis, otherwise 'normal'. I'll be happy to submit a PR to add this functionality.

まず、この JavaScript リポジトリで box-trace の whisker 計算と対数スケールの軸の処理を見つけてください。提案されている distribution API と、normal、log-normal、auto に期待される動作についてメンテナーと確認してください。対数軸上の box plot が適切な whisker の境界を使用し、負の下限を持たず、この動作をテストでカバーできれば完了です。
