这是代码

.....

var annotations = [
  { start: ['1992', 'start'], end: ['1992', 'end'] },
  { start: ['1994', 'start'], end: ['1994', 'end'] },
  { start: ['1996', 'start'], end: ['1996', 'end'] },
  { start: ['1999', 'start'], end: ['1999', 'end'] }
]

......

annotations.forEach(f => {
  chart.annotation().line({
    ...f,
    style: { stroke: '#d9d9d9', lineWidth: 1, lineDash: [10, 10] } })
})

chart.render();

盲猜问题，每次重新 render 的时候，需要手动将 annotations clear 掉。

chart.getAnnotationController().clear();
