### SUMMARY Fixes #28204 On a temporal x-axis (any chart using a time grain), Superset hands ECharts `xAxis.type: 'time'`, a continuous linear scale. Bars/points are placed at their exact timestamp, but ECharts auto-computes "nice" tick positions (month boundaries, even N-day divisions) that don't coincide with the actual buckets. With weekly grain this is very visible: a bucket starting `Nov 30` renders right on top of the `Dec` tick, and 5 weekly bars can produce 8 misaligned ticks. Superset already has the right tool for this: the **Force categorical** toggle (`xAxisForceCategoricalControl`), which switches the axis to `type: 'category'` so each bucket becomes a discrete, tick-aligned category. The transform layer already handles temporal data on a categorical axis (the date formatter is selected by column type, not axis type). The only thing blocking these users was the control's `visibility` gate, which only showed the toggle for **Numeric** x-axis columns. This PR expands that gate to include **Temporal** columns, so the toggle is exposed for time-grain charts. The numeric-only "auto-force when sorted" logic in `initialValue` is untouched, so existing temporal charts keep their continuous time scale unless the user explicitly opts in (default stays `false`). ### BEFORE/AFTER SCREENSHOTS OR ANIMATED GIF Before: on weekly grain, the "Force categorical" toggle is hidden for date x-axes, so ticks land between the weekly markers (see [the reporter's screenshots](https://github.com/apache/superset/discussions/18338#discussioncomment-15871141)). After: the toggle appears for temporal x-axes; enabling it renders one category per bucket with aligned, date-formatted ticks. ### TESTING INSTRUCTIONS 1. Create a Bar Chart (or Line/Area/Mixed) with a temporal x-axis and **Week** time grain. 2. Confirm a new **Force categorical** checkbox now appears under the Query section (it previously only showed for numeric x-axes). 3. Enable it and verify each weekly bucket gets its own tick, with labels formatted as dates and aligned to the bars/markers. ### ADDITIONAL INFORMATION - [x] Has associated issue: Fixes #28204 - [ ] Required feature flags: - [x] Changes UI - [ ] Includes DB Migration (follow approval process in [SIP-59](https://github.com/apache/superset/issues/13351)) - [ ] Migration is atomic, supports rollback & is backwards-compatible - [ ] Confirm DB migration upgrade and downgrade tested - [ ] Runtime estimates and downtime expectations provided - [ ] Introduces new feature or API - [ ] Removes existing feature or API 🤖 Generated with [Claude Code](https://claude.com/claude-code) -- This is an automated message from the Apache Git Service.
