var mulitplColors = [
        ['#9dc6f2','#6fabf3','#3e8ef3','#166ed5'],
        ['#dbc1fe','#c8a3fa','#b881fd','#a961f5'],
        ['#ffcdc5','#f8bba4','#fb9e8e','#f98471'],
        ['#ffeac1','#ffdda8','#ffd47d','#ffc762'],
        ['#aef3e5','#8bf1dc','#60e9cf','#1bcfb0']
    ];

设置样式

layer.setOptions({
            unit: 'meter',
            mode: 'count',
            style: {
                color: function (obj) {
                    let value = obj.rawData[0];
                    let colorLevel = Math.floor(value.v / 0.3);
                    if(colorLevel > 3){
                        colorLevel = 3
                    }
                    return colorsList[value.c][colorLevel];
                },
                radius: 80,
                opacity: 0.7,
                gap: 8,
                height: [0, 0]
            }
        });
