There was a problem hiding this comment.
Before I add any tests or open PRs in vega, I want to check if this is the behavior (a third legendType called discrete) we want as a public API, or if this was supposed to be a private/internal API.
The discrete legend type was added by @jheer in vega/vega@ddd2bbf , so I'll bring it up as a separate issue in the vega repo vega/vega#3954 .

Motivation
quantileandquantizecolor scales #9399Testing
gradientLengthproperty should be respected for a color legend that uses quantile, quantize, or threshold scales.300, and the legend should get taller.{ "$schema": "https://vega.github.io/schema/vega-lite/v5.json", "data": {"url": "data/cars.json"}, "mark": "rect", "encoding": { "y": {"field": "Origin", "type": "nominal"}, "x": {"field": "Cylinders", "type": "ordinal"}, "color": { "aggregate": "mean", "field": "Horsepower", "scale": {"type": "quantile"}, "legend": {"gradientLength": 30} } }, "config": {"axis": {"grid": true, "tickBand": "extent"}} }Notes
vega-liteso this PR can be reviewed. However, we could make the diff in this repo smaller if we instead push a change to theLegendTypefield inside ofvegainstead.
