It seems you're experiencing an issue with how the drill-down chart's "Back" button behavior interacts with the layout when multiple ECharts instances are present in the same table row. The behavior you're describing suggests that the setOption method on one chart is inadvertently applying options from another chart.

Here’s a breakdown of potential causes and solutions:

Potential Causes Shared State Between Chart Instances:

If you are reusing variables like option or initializing multiple charts with overlapping configurations, the instances may interfere with each other. DOM Selection Issues:

Using duplicate id attributes or ambiguous DOM queries could lead to the wrong chart being affected by events like setOption. Improper Event Binding:

If event listeners (myChart.on) are not scoped correctly to specific chart instances, they might interfere when multiple charts are rendered.
