单容器多grid与其他容器联动，只有第一个grid可以联动echarts 折线配置项内容和展示

单容器多grid与其他容器联动，只有第一个grid可以联动，想实现所有grid与其他容器一起联动

      var count = 70;
var intervalCount = 67;
var baseTop = 70;
var gridHeight = 60;

    o1: [],
    o2: [],
    o3: [],
    o4: [],
    o5: [],
    xMin: 0,
    xMax: count
};

for (var i = 0; i < count; i++) {
    var now = i;
    data.o1.push([now, Math.floor(Math.random() * 2)]);
    data.o2.push([now, Math.floor(Math.random() * 2)]);
    data.o3.push([now, Math.floor(Math.random() * 2)]);
    data.o4.push([now, Math.floor(Math.random() * 2)]);
    data.o5.push([now, Math.floor(Math.random() * 2)])
