@antv/g2plot，散点气泡图中的四象限图，怎么监听每个象限的点击事件，产品需要拿每个象限的点击事件去做业务
目前试过通过添加下面的方法，不行
scatterPlot.on('element:click', (evt) => {
const xBaseline = 4;
const yBaseline = 4;

const data = evt.data.data;
const x = data[scatterPlot.options.xField];
const y = data[scatterPlot.options.yField];

if (x > xBaseline && y > yBaseline) {
console.log('点击了热门市场象限');
} else if (x < xBaseline && y > yBaseline) {
console.log('点击了潜力市场象限');
} else if (x < xBaseline && y < yBaseline) {
console.log('点击了提频市场象限');
} else if (x > xBaseline && y < yBaseline) {
console.log('点击了空白象限');
}
});

完整代码如下：
