Looks like this comes from Vega ```json { "$schema": "https://vega.github.io/schema/vega/v5.json", "padding": 5, "height": 100, "width": 100, "scales": [ { "name": "s", "type": "linear", "domain": [0.5, 0.5], "range": [{"signal": "height"}, 0],...

I agree that it's not super convenient but it's unclear where the line should switch from continuous to stroked. Also, this will need to be done in Vega and would...

I think adding new methods to the expression language is easy and we should do it if there is a good use case.

In general, expression functions that are stand alone should be easy to add but anything that interacts with marks and rendering will be trickier to get right.

Did https://github.com/vega/vega/blob/main/packages/vega-scale/README.md help? What did you try? Would d3 work for you instead (which Vega uses internally)?
