Looks good. if (dataZoomModel.get('showDetail')) is not a mistake. It's just the old logic only used dataInterval to display the labels and didn't save it to_dataRange.

Seems the valueRange is updated after the action being dispatched. I guess in the event startValue and endValue will not be the latest value? A test will be good to verify it

Any update on this PR? This would be really helpful as there's merely no way to map start/end percentage to values in the same way as ECharts does accurately.

@pissang @Ovilia @plainheart The missing person has returned, Sorry I haven't checked this in time, had very busy two months.

The timing for calculating _valueRange has moved after the calculation of range. This might be the better way, cause dataZoom event rely on range as well as _valueRange, so this two variable could be calculated at same time

By the way, if an xAxis.type is set to time, a dataZoom.startValue and dataZoom.endValue properties will return formatted values, which makes it difficult to map them back to the original data. For example, if your dataset value is 1682850281010, the dataZoom.startValue will be 1682850281399.8394. Even if you use an ISO string format instead of a timestamp, the dataZoom object will still return a formatted value
