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!

首先，在链接的 CodePen 中复现工作日 boxplot 的案例，并将其与 layout.xaxis.range 文档进行比较。跟踪类别轴边界如何应用于 boxplot trace，然后确定边缘截断是预期行为还是应当修正；当所报告的案例具有明确的受支持行为，且不需要别扭的手动索引调整时，即视为完成。
