Boxplot Category Cutoff Issues

Hi--I've got a boxplot I want to show all options of a category array on, regardless of whether data is present. For the purposes of demonstration, let's consider the categories to be days of the week, and it's important that the user be able to see if a day of the week is missing data.

I can use category array to get missing boxes that fall in the middle of the data to appear, but entries at the start / end won't show up:

I can specify a manual range (in terms of the indexes per docs), but then the boxes get cut off awkwardly (same thing would happen on the right if Sunday was present):

This gets even worse when there are multiple traces (in this case a full box from one trace is cut off):

The only way I see to resolve this is to use negative indexes (or extra indexes if the issue is on the right side), but that doesn't seem very future proof (since it bucks the docs), and sits a bit awkwardly.

Is there a better way to do this?

Here's a codepen reproducing the graphs I used here: https://codepen.io/lswainemoore/pen/yyLOdbo.

Thanks for any help!

まず、リンクされた CodePen の平日別 boxplot のケースを再現し、layout.xaxis.range のドキュメントと比較します。カテゴリ軸の範囲が boxplot トレースにどのように適用されるかを追跡し、そのうえで端の切り捨てが想定されたものか、修正すべきものかを判断します。報告されたケースが、煩雑な手動のインデックス調整なしに、明確にサポートされた動作を示せば完了です。
