描述

grafik
I'm currently using the parallel categories plot in plotly express to display and compare different rankings of elements. I know I'm slightly misusing this plot here, but I still think that my problem should be relevant to others as well. In the example I attached, for simplicity I'm only showing one ranking ("Ranking 1"), where competitor 0 is on the first place and the other competitors share second place. In practice, I would do this with multiple rankings as parallel coordinates, which usually have fewer and fewer distinct ranks going from left to right. As you can also see in the image, the competitors on rank 2 have a weird ordering for some reason, which is why I'm writing here. The dataframe I'm using here looks like this:
index Name Ranking 1
0 0 1
1 1 2
2 2 2
3 3 2
4 4 2
5 5 2
6 6 2
7 7 2
8 8 2
9 9 2
10 10 2
11 11 2
12 12 2
13 13 2
14 14 2
15 15 2
16 16 2
17 17 2
18 18 2
19 19 2
20 20 2
21 21 2

While I usually change some parameters, it looks exactly like this when just calling px.parallel_categories(px). So I really don't see why any of the connecting lines are overlapping. It would be great if I could use this plot like this without creating extra confusion coming from crossing lines.

I used version 5.9 before, but just updated to the latest version (5.18.0) and the issue remains.

调研方向

从 parallel categories 的入口开始,使用 issue 中显示的 dataframe,通过 px.parallel_categories(px) 和附带的示例进行对比,复现报告的输出。跟踪相同 rank 值的排序和渲染方式,然后根据报告中相交或重叠的线验证结果;如果能够确定相关的测试位置,则为此情况添加 coverage。
