## Summary - render placeholder heatmap cells for empty values so splitArea bands do not leak through and create inconsistent empty-cell backgrounds - add a regression test covering the empty heatmap splitArea behavior ## Root Cause Empty heatmap cells on cartesian-style heatmaps were skipped entirely. With `splitArea` enabled, the alternating axis background showed through those skipped cells, so adjacent empty cells could appear inconsistent. ## Validation - `./node_modules/.bin/jest --config test/ut/jest.config.cjs --runInBand test/ut/spec/series/heatmap.test.ts` - `./node_modules/.bin/eslint src/chart/heatmap/HeatmapView.ts test/ut/spec/series/heatmap.test.ts` Fixes #21290 -- This is an automated message from the Apache Git Service.
