Scookie commented on issue #7853: 使用dataset和time，在多个维度时异常 URL: https://github.com/apache/incubator-echarts/issues/7853#issuecomment-434972128 you can do it according to the following way. 你可以试试下面的方法. ``` option = { legend: {}, tooltip: {}, dataset: { source: [ ['time', 'pay', 'income'], ['2017/5/3', 43.3, 85.8], ['2017/5/4', 83.1, 73.4], ['2017/5/5', 86.4, 65.2], ['2017/5/6', 72.4, 53.9] ] }, xAxis: {type: 'time'}, yAxis: {}, series: [ { type: 'line', name:"pay", encode:{ x:"time", y:"pay" } }, { type: 'line', name:"income", encode:{ x:"time", y:"income" } } ] } ```  Or you can do it like this. 或者你也可以优化下写成这样 ``` let data = [ ['time', 'pay', 'income'], ['2017/5/3', 43.3, 85.8], ['2017/5/4', 83.1, 73.4], ['2017/5/5', 86.4, 65.2], ['2017/5/6', 72.4, 53.9] ]; let dimensions = data[0]; let timeKey = "time"; let series = []; dimensions.forEach(item => { if(item != timeKey){ series.push({ type: 'line', name:item, encode:{ x:timeKey, y:item } }); } }) option = { legend: {}, tooltip: {}, dataset: { source: data }, xAxis: {type: 'time'}, yAxis: {}, series: series } ```
