echarts多图联动tooltip不联动？

Question

为什么我的echart多图联动，只有鼠标移动到最后一个图的时候才会显示tooltip，而不是所有图鼠标移动到上面都能显示toolip呢，怎么能移动到每个图表都显示联动的tooltip呢

版本：3.8.4
另外建议官网下载的echarts.js带version注释

 <script>
        $(function(){
            var myChart1 = echarts.init(document.getElementById('main1')); 
                var myChart2 = echarts.init(document.getElementById('main2')); 
                var myChart3 = echarts.init(document.getElementById('main3')); 
                var myChart4 = echarts.init(document.getElementById('main4')); 
 
                // myChart1.setTheme("macarons");
                // myChart2.setTheme("macarons");
                // myChart3.setTheme("macarons");
                // myChart4.setTheme("macarons");
