});项目动态填充数据：

function setBZChart() { var timestart = document.getElementById("timeyearBZ").value; $.ajax({  //ajax动态取值 url: "/FSUManage/Sumstatistics/JsonAuditIndex", data: { CityId: 0, Areaid: 0, Month: timestart }, type: "post", success: function (res) { var returnres = $.parseJSON(res); if (returnres.code == 0) { setTimeout(function () { option = { legend: {}, tooltip: { trigger: 'axis', showContent: true }, dataset: { source: [ //后台动态拼接好json字符串直接赋值source returnres.xaxis, returnres.data, returnres.data1, returnres.data2 ] }, xAxis: { type: 'category' }, yAxis: { gridIndex: 0 }, grid: { top: '45%', containlable: true }, series: [ { type: 'line', smooth: true, seriesLayoutBy: 'row', emphasis: { focus: 'series' } }, { type: 'line', smooth: true, seriesLayoutBy: 'row', emphasis: { focus: 'series' } }, { type: 'line', smooth: true, seriesLayoutBy: 'row', emphasis: { focus: 'series' } }, { type: 'pie', id: 'pie', radius: '30%', center: ['50%', '25%'], emphasis: { focus: 'data' }, label: { formatter: '{b}: ({d}%)' }, encode: { itemName: 'product', value: '1月', tooltip: '1月' } } ] }; myChart.on('updateAxisPointer', function (event) { var xAxisInfo = event.axesInfo[0]; if (xAxisInfo) { var dimension = xAxisInfo.value + 1; myChart.setOption({ series: { id: 'pie', label: { formatter: '{b}: ({d}%)' }, encode: { value: dimension, tooltip: dimension } } }); } });

myChart.setOption(option); }) } else { layer.msg("获取失败", { icon: 5 }); } } });
