ECharts在地图上绘制多个多边形（polygon）的问题

这个官方demo模拟了在百度地图上绘制多边形（polygon）。
Examples - Apache ECharts

但我的需求是绘制多个，而不是1个。
我首先测试这样写，可以看到效果没有问题。
function renderItem(params, api) {
var coords = [
,
,
,
,

];
var points = [];
for (var i = 0; i < coords.length; i++) {
points.push(api.coord(coords));
}
var color = api.visual('color');
return {
type: 'polygon',
shape: {
   points: echarts.graphic.clipPointsByRect(points, {
   x: params.coordSys.x,
   y: params.coordSys.y,
   width: params.coordSys.width,
   height: params.coordSys.height
   })
},
style: api.style({
   fill: color,
   stroke: echarts.color.lift(color)
})
};
}

function renderItem2(params, api) {
var coords = [
,
,

];
var points = [];
for (var i = 0; i < coords.length; i++) {
points.push(api.coord(coords));
}
var color = api.visual('color');
return {
type: 'polygon',
shape: {
   points: echarts.graphic.clipPointsByRect(points, {
   x: params.coordSys.x,
   y: params.coordSys.y,
   width: params.coordSys.width,
   height: params.coordSys.height
   })
},
style: api.style({
   fill: color,
   stroke: echarts.color.lift(color)
})
};
}
option = {
backgroundColor: 'transparent',
title: {
text: '全国主要城市空气质量',
subtext: 'data from PM25.in',
sublink: 'http://www.pm25.in',
left: 'center',
textStyle: {
   color: '#fff'
}
},
tooltip: {
trigger: 'item'
},
bmap: {
center: ,
zoom: 5,
roam: true
},
series: [
{
   type: 'custom',
   coordinateSystem: 'bmap',
   renderItem: renderItem,
   itemStyle: {
   opacity: 0.5
   },
   animation: false,
   silent: true,
   data: ,
   z: -10
},{
   type: 'custom',
   coordinateSystem: 'bmap',
   renderItem: renderItem2,
   itemStyle: {
   opacity: 0.5
   },
   animation: false,
   silent: true,
   data: ,
   z: -10
}
]
};

但以上写法，代码是重复的，我希望复用renderItem函数，经过多次测试，我发现这样ECharts只会渲染最后一个多边形（polygon）。
let coords;
function renderItem(params, api) {
var points = [];
for (var i = 0; i < coords.length; i++) {
   points.push(api.coord(coords));
}
var color = api.visual('color');
return {
   type: 'polygon',
   shape: {
         points: echarts.graphic.clipPointsByRect(points, {
            x: params.coordSys.x,
            y: params.coordSys.y,
            width: params.coordSys.width,
            height: params.coordSys.height
         })
   },
   style: api.style({
         fill: color,
         stroke: echarts.color.lift(color)
   })
};
}

option = {
backgroundColor: 'transparent',
title: {
   text: '全国主要城市空气质量',
   left: 'center',
   textStyle: {
         color: '#fff'
   }
},
tooltip: {
   trigger: 'item'
},
bmap: {
   center: ,
   zoom: 5,
   roam: true
},
series: []
};

const arrCoords = [
[
   ,
   ,
   ,
   ,

], [
   ,
   ,

]
];

arrCoords.forEach(element => {
coords = element;

option.series.push({
   type: 'custom',
   coordinateSystem: 'bmap',
   renderItem: renderItem,
   itemStyle: {
         opacity: 0.2
   },
   animation: false,
   silent: true,
   data:
});

});

所以，正确的写法应该是怎样？
请大佬指教，感谢。
提醒：将以上代码复制到官方demo页面，即可复现。

看到你这个，我也想问一个问题，如果坐标点的顺序是乱的。形成的多边型就会交叉。
例如：
var coords = [
,
,
,
,

];

你好，我是按照官方的改的。

但如果我要创建多个多边形，renderItem函数如果不能复用，代码非常冗余且不利于维护。

看上去说得头头是道，实际没啥用。你传入的 renderItem 是一个function ，你在function定义了 coord 而coord做全局变量。你做coords一万次循环也是最后一个coord。简单就是你确实引入了2个，只是这两个坐标一致，重叠在一起而已。好好按官方做别整花里胡哨的
