Summary
Fixes #248867
This PR extends the Lens API's XY chart schema and state-to-API conversion logic to support
colorMappingon thebreakdown_byfield in ES|QL data layers. Previously,colorMappingwas only supported on thebreakdown_byfield for non-ES|QL (form-based) XY data layers. ES|QL layers used a plainesqlColumnSchemaforbreakdown_by, which did not allow specifying color mapping configuration.What changed
Two files were modified:
Schema (
config_builder/schema/charts/xy.ts): Thebreakdown_byfield inxyDataLayerSchemaESQLwas changed from a plainesqlColumnSchemato an extended version that adds an optionalcolor: colorMappingSchemaproperty — mirroring the pattern already established in the non-ES|QL layer (xyDataLayerSchemaNoESQL) and other chart types (pie, treemap, waffle, mosaic, tagcloud, datatable).Transform (State → API) (
config_builder/transforms/charts/xy/api_layers.ts): TheconvertDataLayerToAPIfunction's ES|QL branch (theTextBasedLayercode path) now includescolorMappingfrom the visualization state when constructing thebreakdown_byobject in the API output, using the existingfromColorMappingLensStateToAPIutility. This ensures round-trip fidelity: when an ES|QL XY layer has acolorMappingconfiguration, it is correctly serialized into the API format.No changes needed for the reverse direction (API → State): The
buildDataLayerfunction instate_layers.tsalready handlescoloronbreakdown_bygenerically via'color' in layer.breakdown_by, so the existing code at lines 92–94 already picks up the new field and converts it usingfromColorMappingAPIToLensState.
