Custom axis sort (vega-lite)?

[juliett...@gmail.com]

Is it possible to manually sort an axis in vega-lite? I.e., not ascending or descending, but for example {"sort": [fieldA, fieldB, fieldD, fieldC]}?

Thanks.

Hi ,

As mention in the sort documentation, you can specify custom sort order by providing custom scale domain:

{field:..., type: ..., "scale": {"domain": ["a", "b", "c"]}}

Note that we're actively updating the docs for our 2.0 release, so a lot of pages will be improved (if they haven't) in the next few weeks.  

Best,

Kanit

I am trying to sort it so the color order (bottom to top/top to bottom doesn't matter) is "None", "Minor", "Medium", "Substantial".

However, this currently doesn't change that, it is currently still alphabetical with Medium on top and Substantial on the bottom. How do I fix that? 

Thanks for your help.

If you want to order the color in the legend, then scale.domain works in the latest Vega-Lite version. 

Here is a screenshot from the online editor (backup link)

If you want to sort the stack order of the marks, you can see a workaround here:  https://github.com/vega/vega-lite/issues/1734#issuecomment-263481177.
