### Steps to Reproduce

I've attached the entire EChartsOption object and el element and sizes for both cases: the bug/invalid with 1 element on series, and the normal case that have more than only one element on series and works perfectly as expected

### Current Behavior

I don't know why, but when there's only one element in my chart, the zoom on the x-axis breaks and goes into an invalid position fallback (top right). However, if there's more than one element, then mysteriously it works correctly as it should and centers at the bottom.

### Expected Behavior

The normal and logical operation is that it functions as programmed and is placed at the bottom center.
