Here's the code snippet I ended up with ftw
```ts
highlightPortfolio(event: ECElementEvent & { batch:
LabelLayoutOptionCallbackParams[]}) {
const { seriesIndex = 0, dataIndex = 0 } = event.batch[0];
const height = this.chartInstance.getHeight();
const options = this.chartInstance.getOption();
const { value } = (options['series'] as
any)[seriesIndex].data[dataIndex];
const pixels = this.chartInstance.convertToPixel({ seriesIndex }, value
as number[]);
const isLow = pixels[1] > height / 2;
this.chartInstance.setOption({
series: {
emphasis: {
label: {
position: isLow ? 'top' : 'bottom',
offset: isLow ? [0, -5] : [0, 5],
},
},
},
});
}
```
