echarts.js的基础
最近在做一个体检的项目，有数据分析的模块，用到了echarts这个插件，记录一下下咯！
1.引入js
<script src="/public/dist/js/echarts.js">script>2.在dom中插入chart
<div id="pie">
<div id="pieChart" style="width:650px;height:300px;"div>
div>3.初始化chart
var myChartNum = echarts.init(document.getElementById("num"));4.初始化配置
option = {
title : {
text: '某地区蒸发量和降水量',
subtext: '纯属虚构'
},
tooltip : {
trigger: 'axis'
},
legend: {
data:['蒸发量','降水量']
},
toolbox: {
show : true,
feature : {
mark : {show: true},
dataView : {show: true, readOnly: false},
magicType : {show: true, type: ['line', 'bar']},
restore : {show: true},
saveAsImage : {show: true}
}
},
calculable : true,
xAxis : [
{
type : 'category',
data : ['1月','2月','3月','4月','5月','6月','7月','8月','9月','10月','11月','12月']
}
],
yAxis : [
{
type : 'value'
}
],
series : [
{
name:'蒸发量',
type:'bar',
data:[2.0, 4.9, 7.0, 23.2, 25.6, 76.7, 135.6, 162.2, 32.6, 20.0, 6.4, 3.3],
markPoint : {
data : [
{type : 'max', name: '最大值'},
{type : 'min', name: '最小值'}
]
},
markLine : {
data : [
{type : 'average', name: '平均值'}
]
}
},
{
name:'降水量',
type:'bar',
data:[2.6, 5.9, 9.0, 26.4, 28.7, 70.7, 175.6, 182.2, 48.7, 18.8, 6.0, 2.3],
markPoint : {
data : [
{name : '年最高', value : 182.2, xAxis: 7, yAxis: 183, symbolSize:18},
{name : '年最低', value : 2.3, xAxis: 11, yAxis: 3}
]
},
markLine : {
data : [
{type : 'average', name : '平均值'}
]
}
}
]
};5.填充chart
myChartNum.setOption(option);项目中具体的例子：
//统计图
$(function () {
var medical_id = 1;
var starttime = '';
var endtime = '';
var corporate = '';
dataAjax(medical_id,starttime,endtime,corporate);
function dataAjax(medical_id,starttime,endtime,corporate){
$.ajax({
url: "/analyze/data",
type: "post",
data:{
medical_id:medical_id,
starttime:starttime,
endtime:endtime,
corporate:corporate
},
dataType: "json",
success: function(msg) {
//status=0:刷新页面 status=1：选择时间 status=2：选择时间和公司
var jsons = msg;
var status = jsons.status;
if(status == 0){
$('.bar').hide();
$('.pie').show();
setPie(jsons);
}else if(status == 1){
$('.bar').show();
$('.pie').show();
setNum(jsons);
setPie(jsons);
}else if(status == 2){
$('.bar').show();
$('.pie').hide();
setNum(jsons);
}else{
$('.bar').hide();
$('.pie').hide();
$('.errorBox').hide().fadeIn(500);
}
}
});
}
function setNum(jsons) {
// function GetDateStr(AddDayCount) {
// var dd = new Date();
// dd.setDate(dd.getDate()+AddDayCount);//获取AddDayCount天后的日期
// var y = dd.getFullYear();
// var m = dd.getMonth()+1;//获取当前月份的日期
// var d = dd.getDate();
// return m+"月"+d+"日";
// }
//柱状图
var myChartNum = echarts.init(document.getElementById("num"));
