### Version 6.0.0 ### Link to Minimal Reproduction https://echarts.apache.org/examples/en/editor.html?code=hZC7CoMwFIZ3n-JsLg6tvSApHXqdhC7dikOKBw2kSdBoKcV3byJeqlSaJcn5P_4PjlSaSQFbeDsAOWYMcwI384Z6Yo9-KSTgKoau14xoKVkc0jvyS4kZp4qAzgpsY24T0hWY4lQ-hwiAkjmzblMtC52zuK83As4ScZUmq7tCJtBtwmpgsck_E0eR6JTAfDWe-QT8YNwbU03bHdR7gJLywliWMw8Efdhl7Nye_yIWQUfsJwi_Iw4TRG85_ib83nKaINYdcTZEA0T1bX-RU20-&enc=deflate ### Steps to Reproduce 1. Create a pie chart with external labels. 2. Use the following option: ```js option = { series: [{ type: 'pie', avoidLabelOverlap: true, label: { show: true, position: 'outside', alignTo: 'labelLine' }, labelLine: { show: true, length: 15, length2: 28 }, data: [ { value: 40, name: 'A' }, { value: 38, name: 'B' }, { value: 32, name: 'C' }, { value: 30, name: 'D' }, { value: 28, name: 'E' }, { value: 26, name: 'F' } ] }] }; ``` 3. Observe the label layout. 4. Change only label.position from 'outside' to 'outer': ```js label: { show: true, position: 'outer', alignTo: 'labelLine' } ``` 5. Observe that the labelLine alignment behavior changes. ### Current Behavior When `series-pie.label.position` is set to `'outside'`, `label.alignTo: 'labelLine'` does not appear to apply the same label-line alignment behavior. Changing only `label.position` from `'outside'` to `'outer'` makes the `labelLine` alignment behavior work. ### Expected Behavior If `'outside'` is a supported alias for external pie labels, it should behave the same as `'outer'` for `label.alignTo: 'labelLine'`. Alternatively, if only `'outer'` is intended to support `alignTo`, the docs/types should make that distinction clear. ### Environment ```markdown - OS: macOS 26.4.1 (Build 25E253) - Browser: Chrome 148.0.7778.168 - Framework: none / plain ECharts option in the official editor - Node: v22.22.1 - npm: 10.9.4 ``` ### Any additional comments? This seems to be an alias inconsistency between `outside` and `outer`. In the current `master` branch (`d6a812f8482f23933692ce3ab99d8bf73131835f`), `PieSeries.ts` allows both values, but `labelLayout.ts` only checks `position === 'outer'` for the `alignTo: 'labelLine'` branch. As a workaround, mapping `label.position: 'outside'` to `'outer'` before passing the option to ECharts makes it work. -- This is an automated message from the Apache Git Service.
