How can I configure on additional X Axis on Workshop Chart XY Widgets?

In Workshop, I’m display some data with a X axis that is time (e.g. days) and a Y axis that is some value (e.g. count of objects).

I would like to display a second X axis, to show the time in a different bucketing (e.g. weeks) as well, like this:

Is it possible ? How to build it ?

Workshop does display multiple time axis when for instance the bucketing is by month, and data spans over multiple years, and it’s wide enough to display both months and years. I don’t think it displays weeks though.
If you need something more custom, you should look into using Vega Charts which now have a dedicated Workshop widget: https://www.palantir.com/docs/foundry/workshop/widgets-vega-chart/
