{
  "$schema": "https://vega.github.io/schema/vega-lite/v3.json",
  "repeat": {"column": ["Horsepower","Miles_per_Gallon", "Acceleration"]},

Odd. To debug this, we should print the dataflow before optimizations and see whether necessary nodes get removed from it.

scale_child_Miles_per_Gallon_child_main

It's related to scale rename

I am having the same problem while trying to use repeat and facet together. It seems this bug has been open for long time, is there a plan to fix it officially in future?

[domoritz]

Yes, I plan to get to these issues this quarter.

I'm having what looks like the same problem here as well, trying to use both repeat and a facet. Any update or pointers to a workaround? Thanks!

[domoritz]

I got swamped with other things to work on. I don't have an update yet.
