在設置中設置去除

geo: {
        map: 'china',
        label: {
            emphasis: {
                show: false
            }
        },
        regions: [
            {
                name: '南海諸島', 
                value: 0, 
                itemStyle: 
                    {normal: 
                        {opacity: 0,
                        label: {
                            show: false
                            
                        }
                    }
                }
            }],
        roam: true,
        itemStyle: {
            normal: {
                areaColor: '#323c48',
                borderColor: '#404a59'
            },
            emphasis: {
                areaColor: '#2a333d'
            }
        }
    },

或者在數據中把南海地圖隱藏

{"name": "南海諸島","value": 0, "itemStyle":{ "normal":{"opacity":0}} }
