  const yIndex = chart.convertFromPixel(
   {
      seriesIndex: 0
    },
    pointInPixel
  )[1];
  const yData = options.yAxis.data[yIndex];
  console.log(yIndex, options);

converFromPixel 返回的是数据并不是索引，是否是小数取决于 y 轴数据类型

我看官方文档上写的叫刻度值。“[300, 900] 表示该点 x 轴上对应刻度值 300，y 轴上对应刻度值 900”。刻度值是什么意思？如果yAxis是category类型的，那刻度值怎么和索引值对应上呢？ https://echarts.apache.org/examples/zh/editor.html?c=bar-rich-text
