Steps to Reproduce

1. 使用 TypeScript
2. 调用 instance.getOption() 返回类型提示是 ECBasicOption，但实际返回类似于 { title: [{...}], legend: [{...}], grid: [{...}] }
3. 所以使用 instance.getOption().legend[0] 会提示类型错误 元素隐式具有 "any" 类型，因为类型为 "0" 的表达式不能用于索引类型 "{}"。 类型“{}”上不存在属性“0”。

Current Behavior

instance.getOption() 返回类型错误

Expected Behavior

instance.getOption() 返回类型和实际一至

Current Behavior

instance.getOption() returns the wrong type

Expected Behavior

instance.getOption() return type and actual one to
