    };
    option.visualMap = visualMap2;
    chart.setOptions(newOptions);
}

假设用户数据返回的visualMap属性是数组，则对于重置visualMap属性，则需要替换成以下方式：

var visualMap2 = [{
        show: false,
        min: 8,
        max: 1532696,
        dimension: 2,
        calculable: true,
        precision: 0.01,
            inRange: {
                color: ['#dd4444', '#fec42c', '#80F1BE', '#c12e34', '#e6b600', '#0098d9', '#2b821d', '#005eaa', '#339ca8', '#cda819', '#32a487'],
                symbolSize: [10, 50]
            }
    }];
