### SUMMARY Time-shift (time-comparison) line charts intermittently render partially in PDF/PNG email reports and thumbnails — the line "breaks off" or the chart is blank. **Root cause:** report screenshots capture the chart while ECharts is still animating. The screenshot path has no render-complete signal — it just waits a fixed timeout, which loses the race under load (and the time-comparison series, drawn last, is the first to be cut off). Bumping the timeout only masks it. **Fix:** disable the ECharts draw animation in report/thumbnail standalone mode (`standalone=true` / `3`), reusing the existing `isDashboardRefreshing` animation override. Static images don't need animation, so the chart is final before capture. Interactive/embed rendering is unchanged. ### BEFORE/AFTER - Before <img width="1600" height="1200" alt="partial" src="https://github.com/user-attachments/assets/1e9c0193-66cb-47af-a9f1-b94caf77a91b"; /> - After <img width="1600" height="1200" alt="fixed_race0" src="https://github.com/user-attachments/assets/dbfb46bd-40f4-47f6-8bef-dbeccb8f1f40"; /> ### TESTING INSTRUCTIONS - `cd superset-frontend && npm run test -- plugins/plugin-chart-echarts/src/components/Echart.test.tsx` - Or manually: create a time-shift line chart, add it to a report, send as PNG/PDF; the full chart (base + shifted series) renders every time. -- This is an automated message from the Apache Git Service.
