echarts 处理数据

假如 我数据是这样式的 一个数组里边包含两个对象

var data = [{ "gender": "female", "height": 161.2, "weight": 51.6 }, { "gender": "female", "height": 167.5, "weight": 59 }] 

想转换成二维数组【两种方法】
for循环遍历 再push一下

 var data = [{ "gender": "female", "height": 161.2, "weight": 51.6 }, { "gender": "female", "height": 167.5, "weight": 59 }, ]
        console.log(data);
        // 处理数据 要求二维数组
        let axdata = []
        for(var i = 0; i<data.length;i++){
            let height = data[i].height
            let weight = data[i].weight
            let newArr = [height,weight]
            axdata.push(newArr)
        }
        console.log(axdata);

用map

  var data = [{ "gender": "female", "height": 161.2, "weight": 51.6 }, { "gender": "female", "height": 167.5, "weight": 59 },]
        console.log(data);
        // 转换二维数组
        var scatterData = data.map(function (item) {
            return [item.height, item.weight]; // 将每个对象的height和weight作为散点坐标  
        });
        console.log(scatterData);
