应用场景：一些柱形图在数据量比较多的时候，横向排列受到挤压，导致柱形图，变的非常细，影响整体的效果。所以应该将柱形图堆叠起来，这样就会好很多。
先上效果图：
关键字：series-stack
//数据堆叠，同个类目轴上系列配置相同的stack值后，后一个系列的值会在前一个系列的值上相加。
var option = {series: [{name: "钢铁侠",type: "bar",//柱状图stack:"Search Engine",emphasis: {//折线图的高亮状态。focus: "series",//聚焦当前高亮的数据所在的系列的所有图形。},data: [320, 332, 301, 334, 390, 330, 320],},{name: "蜘蛛侠",type: "bar",stack: "Search Engine",emphasis: {focus: "series",},data: [120, 132, 101, 134, 90, 230, 210],},{name: "绿巨人",type: "bar",stack: "Search Engine",//数据堆叠，同个类目轴上系列配置相同的stack值后，后一个系列的值会在前一个系列的值上相加。emphasis: {focus: "series",},data: [220, 182, 191, 234, 290, 330, 310],},{name: "黑寡妇",type: "bar",stack: "Search Engine",emphasis: {focus: "series",},data: [150, 232, 201, 154, 190, 330, 410],},{name: "鹰眼",type: "bar",stack:"Search Engine",data: [862, 1018, 964, 1026, 1679, 1600, 1570],emphasis: {focus: "series",},// markLine: {//图表标线// lineStyle: {//标线的样式//type: "dashed",//线的类型:// },// data: [[{ type: "min" }, { type: "max" }]],// },},{name: "雷神",type: "bar",// barWidth: 5,//柱形宽度stack: "Search Engine",emphasis: {focus: "series",},data: [620, 732, 701, 734, 1090, 1130, 1120],},{name: "美国队长",type: "bar",stack: "Search Engine",emphasis: {focus: "series",},data: [120, 132, 101, 134, 290, 230, 220],},{name: "蚁人",type: "bar",stack: "Search Engine",emphasis: {focus: "series",},data: [60, 72, 71, 74, 190, 130, 110],},{name: "黑豹",type: "bar",stack: "Search Engine",emphasis: {focus: "series",},data: [62, 82, 91, 84, 109, 110, 120],},],}
