关于echarts 里tooltip的问题？

Question

场景

如何让图中标识的三个点的tootip同时显示？

const options = {
    tooltip: {
        trigger: 'item',
        borderWidth: 1,
        alwaysShowContent: true,
        backgroundColor: 'rgba(8,104,193, .5)',
        borderColor: '#2172aa',
        padding: [15, 30, 15, 15],
        extraCssText: 'z-index:100',
        formatter: function (params) {
            if (params.data.type != 'other') {
                var data = params.data
                var typeStr
                var limitIPstr = ''
                data.type == 'first' && (typeStr = '最常用IP为')
                data.type == 'second' && (typeStr = '第二常用IP为')
                data.type == 'third' && (typeStr = '第三常用IP为')
                !data.isLimit && (limitIPstr = ',限定IP外')
                var str = typeStr + data.ip + ',IP归属地为' + data.area + limitIPstr
                return str
            }
        }
    },
    geo: {
        map: 'china',
        left: 20,
        top: 20,
        right: 0,
        bottom: 0,
        roam: false,
        layoutCenter: ['50%', '50%'], //地图位置

            },
            itemStyle: {

                borderColor: '#0c80c4',
                borderWidth: 2
            }

                console.log(param);
                console.log('-----');
                (param.data.type == 'first') && (fIndex = param.dataIndex);
                (param.data.type == 'second') && (sIndex = param.dataIndex);
                (param.data.type == 'third') && (tIndex = param.dataIndex);
                return colorOptions[param.data.type];
            },
            shadowBlur: 0,

        },
        emphasis: {
            itemStyle: {
                opacity: 1, //线条宽度
                shadowBlur: 0,

            }
        },
        data: getPonitData(data.pointData)

}

echarts自定义配置是真的难...
你这个地方配置tooltip几乎不可能实现，建议配置series下的label标签，通过label的formatter控制你要显示的内容，然后改下样式，但不一定会有你截图那样美观。
