DorisOu opened a new issue #9335: 建议还是用自定义系列的 polygon 绘制
URL: https://github.com/apache/incubator-echarts/issues/9335
 
 
   当自定义区域的坐标为这样的格式 var paths = [
           [
               [113.447976, 22.363792],
               [113.328872, 22.422652],
               [113.370276, 22.308298],
               [113.474307, 22.260588]
           ],
           [
               [113.55542316292018, 22.451920414231754],
               [113.55552840279444, 22.452818734758235],
               [113.55371761986818, 22.453423869526087],
               [113.55356109301499, 22.454512840320145]
           ]
       ]
   
   renderItem这样写起效果了。但是无法渲染第二数组
   function renderItem(params, api) {
           var coords = paths[0];
           var points = [];
           for (var i = 0; i < coords.length; i++) {
               points.push(api.coord(coords[i]));
           }
           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: 'lightblue',
                   stroke: '#000'
               })
           }
       }
   如何写出复用的函数？
