echarts能提供仅清除series属性的接口吗

[Sakura-gh]

What problem does this feature solve?

使用this.chartInstance.clear()或this.chartInstance.setOption(..., true)都会把原先所有的内容给清空，尤其是在使用百度地图时，由于bmap属性被清除，导致所有自定义样式也会一同消失。如果使用上述两种方法，需要重新加载过多的资源，导致刷新卡顿。目前的需求是仅仅清空原option中的series属性，而不用清除其他属性导致重复加载。

注：我尝试过replaceMerge方法，在没有设置series属性id的情况下，replaceMerge似乎并不能完整地删除原有的series：

console.log(this.chartInstance.getOption())
this.chartInstance.setOption(dataOption, {replaceMerge: 'series'})
console.log(this.chartInstance.getOption())

console输出： 原先的series：

series: Array(2)
0: {name: "飞线", type: "lines", coordinateSystem: "bmap", symbol: Array(2), effect: {…}, …}
1: {name: "终点", type: "effectScatter", coordinateSystem: "bmap", rippleEffect: {…}, symbolSize: 10, …}

setOption之后的series：

series: Array(2)
0: {type: "effectScatter", coordinateSystem: "bmap", animation: true, symbol: "circle", symbolSize: 15, …}
1: {name: "终点", type: "effectScatter", coordinateSystem: "bmap", rippleEffect: {…}, symbolSize: 10, …}

新的series只包含0: {type: "effectScatter", coordinateSystem: "bmap", animation: true, symbol: "circle", symbolSize: 15, …}，显然这个结果是删除了原series中的0: {name: "飞线", type: "lines", coordinateSystem: "bmap", symbol: Array(2), effect: {…}, …}，却保留了不应该保留的1: {name: "终点", type: "effectScatter", coordinateSystem: "bmap", rippleEffect: {…}, symbolSize: 10, …}

What does the proposed API look like?

chartInstance.clearSeries()

**TITLE** Can echarts provide an interface that clears only the series property? **BODY** ### What problem does this feature solve? Using this.chartInstance.clear() or this.chartInstance.setOption(..., true) will clear all the original content, especially when using Baidu map, because the bmap attribute is cleared, all custom styles are also Will disappear together. If you use the above two methods, you need to reload too many resources, resulting in refresh freeze. The current requirement is to only clear the series attributes in the original option, without clearing other attributes to cause repeated loading. ### What does the proposed API look like? chartInstance.clearSeries()

@Sakura-gh echarts 版本是多少呢？

以及， setOption(dataOption, ...) 的 dataOption 是什么内容。

我发现自己使用的是echarts4.9.0版本，好像并不支持replaceMerge参数，以上的情况应该是直接发生了merge和替换

v5 后支持 replaceMerge ，能只清除 series 。
