复现代码

const chart = new Chart({
  container,
  width: 800,
  height: 400,
});
const data = Array.from({ length: 10 }, (e, i) => {
  return {
    x: i,
    y: i,
  };
});
chart.data(data);
const line = chart.line();
line.position('x*y');
line.destroy();
chart.render();

不合法的用法！你需要做什么样的功能？

这是一个最小可复现的 demo，所以显得不合理... 是实际使用中需要添加与删除图形，在删除之后再次添加图形然后调用 render 就会报错

哦哦，好的。

const line = chart.line();
line.position('x*y');
// 从容器中删除（当前没有 api，这么做有点 hack）
chart.geometries = chart.geometries.filter(e => e!== line)
line.destroy();
chart.render();
