Allow transform-based signals to be accessed by the same transform set

Closed this issue · 1 comments

Internal tracking currently prevents some signal accesses when a signal defined as the value of a data transform is subsequently referenced by a transform later in the same pipeline.

Here's an example:

"transform": [
  {"type": "extent", "field": "u", "signal": "extent"},
  {"type": "bin", "field": "u", "extent": {"signal": "extent"}}
]

Fixed in vega/vega-parser@3f05e3c and released in v3.0.0-beta.6.
