From d92e819b5890303f4c72a35fac0482326ddbd269 Mon Sep 17 00:00:00 2001 From: Joe Li Date: Fri, 12 Sep 2025 23:23:10 -0700 Subject: [PATCH 1/2] fix(deck.gl): restore legend display for Polygon charts with linear palette and fixed color schemes MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Fixes a regression in version 6.0 where legends were not displayed for deck.gl Polygon charts when using linear_palette or fixed_color color schemes. The issue was caused by incorrect conditional logic that treated any truthy colorSchemeType as requiring color breakpoints. Changes: - Fix bucket generation logic in Polygon.tsx to specifically check for color_breakpoints scheme - Add comprehensive test suite covering all color scheme types and edge cases - Ensure backward compatibility and preserve existing functionality Fixes: https://github.com/apache/superset/issues/34822 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude --- .../src/layers/Polygon/Polygon.test.tsx | 286 ++++++++++++++++++ .../src/layers/Polygon/Polygon.tsx | 2 +- 2 files changed, 287 insertions(+), 1 deletion(-) create mode 100644 superset-frontend/plugins/legacy-preset-chart-deckgl/src/layers/Polygon/Polygon.test.tsx diff --git a/superset-frontend/plugins/legacy-preset-chart-deckgl/src/layers/Polygon/Polygon.test.tsx b/superset-frontend/plugins/legacy-preset-chart-deckgl/src/layers/Polygon/Polygon.test.tsx new file mode 100644 index 000000000000..b41b82ee1eee --- /dev/null +++ b/superset-frontend/plugins/legacy-preset-chart-deckgl/src/layers/Polygon/Polygon.test.tsx @@ -0,0 +1,286 @@ +/** + * Licensed to the Apache Software Foundation (ASF) under one + * or more contributor license agreements.
