[Bug] Pie: selected slice x/y offset persists after setOption with fewer data items

Version

6.1.0

Link to Minimal Reproduction

https://jsfiddle.net/ma_ss_ai/0kozdxfy/5/

Steps to Reproduce

1. Open the JSFiddle link and Run. Ensure ECharts 6.1.0 is loaded (Resources → CDNJS → echarts 6.1.0).
2. Click 1–2 pie sectors on the chart (not the legend). Slices move outward (selectedMode: 'multiple', selectedOffset: 10).
3. Click "Apply filter (OLD — no unselect)". This calls setOption with fewer series[0].data items, { notMerge: true }, then resize(), without unselect and without resetting graphic x/y on slices.
4. Observe the pie layout: fewer slices, series top/bottom may change; chart can look shifted or misaligned.

Current Behavior

After multi-select, selected slice graphic elements keep non-zero x/y translation when setOption replaces the dataset with fewer items (notMerge: true) and resize() is called.

The pie can appear shifted or misaligned relative to the series layout box. This is more visible when layout margins change (e.g. series top/bottom depend on slice count).

dispatchAction({ type: 'unselect', seriesIndex: 0 }) before setOption does not reset those graphic offsets. Resetting each slice graphic with attr({ x: 0, y: 0 }) before setOption fixes the layout.

Expected Behavior

After setOption with a new dataset, the pie is centered and sector positions match the new layout, with no leftover translation from the previous selection state.

Environment

- OS: macOS
- Browser: Chrome (latest)
- Framework: none (plain JS in JSFiddle; same issue observed in production with echarts 6.1.0 and echarts-for-react)

Any additional comments?

Repro flow mirrors a dashboard widget: multi-select pie sectors → filter data → setOption(notMerge) + resize.

Workaround used in our application:

chart.dispatchAction({ type: 'unselect', seriesIndex: 'all' }, { flush: true }); chart.getModel().getSeries().forEach((series) => { series.getData().eachItemGraphicEl((el) => el?.attr({ x: 0, y: 0 })); }); chart.setOption(newOption, { notMerge: true }); chart.resize();

Screenshot 1: Multi-select two pie sectors (C and E); slices move outward before filtering.

Screenshot 2: After Apply filter (OLD — no unselect) with 2 slices — selected graphic offset persists; pie looks misaligned / fragmented.

Screenshot 3 shows that Reset in the repro only calls dispatchAction(unselect) and setOption(full data); slices stay offset. Matches our finding that graphic x/y must be reset explicitly.
