The `Slice` model only has a handful of actual database columns like `slice_name`, `viz_type`, `params`, `query_context`, `datasource_id`, `cache_timeout`, etc. [[2]](https://github.com/apache/superset/blob/829e4d92d91ceae4b43b1ed3b063ffe45377799c/superset/models/slice.py#L73-L94). Everything else — all the chart configuration — lives inside `params` as a JSON string. Unfortunately, there is **no single definitive list** of what keys go inside `params`. The structure is dynamic and depends on the chart type (viz_type). Each chart plugin defines its own set of controls, and the resulting form data all gets serialized into `params`. The structure has also evolved over time through various migrations [[3]](https://github.com/apache/superset/blob/829e4d92d91ceae4b43b1ed3b063ffe45377799c/superset/migrations/versions/2019-10-10_13-52_1495eb914ad3_time_range.py#L49-L61) [[4]](https://github.com/apache/superset/blob/829e4d92d91ceae4b43b1ed3b063ffe45377799c/superset/migrations/versions/2019-11-06_15-23_78ee127d0d1d_reconvert_legacy_filters_into_adhoc.py#L52-L68). The best way to see what's in there for a given chart is to export it and look at the `params` block in the YAML file. *** Regarding your **2 missing charts on dashboard export**: the export logic pulls charts from the `dashboard_slices` association table via `model.slices` [[5]](https://github.com/apache/superset/blob/829e4d92d91ceae4b43b1ed3b063ffe45377799c/superset/commands/dashboard/export.py#L184-L195) [[6]](https://github.com/apache/superset/blob/829e4d92d91ceae4b43b1ed3b063ffe45377799c/superset/models/dashboard.py#L92-L145). If only 1 chart is exported, the other 2 are likely **not linked in `dashboard_slices`** even though they appear on the dashboard UI (via `position_json`). To debug this, you can run: ```sql SELECT * FROM dashboard_slices WHERE dashboard_id = <your_dashboard_id>; ``` If you see only 1 row instead of 3, that confirms the issue — the other charts aren't properly associated. Removing and re-adding them to the dashboard via the UI should fix it. Also worth noting: there's a [caching issue](https://github.com/apache/superset/issues/41687) where the export endpoint can serve stale ZIPs from browser cache. Try exporting in incognito mode or clearing your cache to rule that out. <!-- Dosu Comment Footer --> *To reply, just mention [@dosu](<https://go.dosu.dev/dosubot?utm_source=github&utm_medium=bot-comment&utm_campaign=github-comment-footer-20260415&utm_content=reply-with-mention&utm_term=apache%2Fsuperset>).* --- Docs are dead.
