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 });
}
}
});
