看了下使用说明，试了半天终于搞对了

参考文档：Documentation - Apache ECharts

option = {xAxis: {type: 'category',data: ['Mon', 'Tue', 'Wed', 'Thu', 'Fri', 'Sat', 'Sun']},yAxis: {type: 'value'},series: [{data: [120, 200, 150, 80, 70, 110, 130],type: 'bar',markArea: {itemStyle: {color: '#ccc'},data: [[{name: '两个坐标之间的标域',coord: ['Mon']},{coord: ['Mon']}],     [{// name: '两个坐标之间的标域',coord: ['Wed']},{coord: ['Wed']}],]},}]
};
