The code is like this

;(function(){ var lineChart = echarts.init(document.getElementById('sparkline')); // 指定图表的配置项和数据 var option = { color: ['#fff'], grid: { bottom: 0, top: 0, left: 0, right: 0 }, tooltip: { show: true, trigger: 'item', formatter: '{b} : {c}' }, xAxis: { show: false, data: ['星期一','星期二','星期三','星期四','星期五','星期六','星期日'] }, yAxis: { show: false }, series: [{ name: '最近7日浏览量', type: 'line', data: [5, 20, 36, 10, 10, 20, 20] }] }; // 使用刚指定的配置项和数据显示图表。 lineChart.setOption(option); })()
