前几天完成了数据库测试的最后的可视化阶段，以及多表联动等功能，对这段时间遇到的问题和学到的东西做个总结整理吧
关于数据的可视化主要学习于百度的开源Examples - Apache ECharts，做了以下几个的案例
圆柱图

<title>圆柱图</title>
<!-- 引入刚刚下载的 ECharts 文件 -->
<script src="JS/echarts.js"></script>
<script src="JS/jquery-3.1.1.js"></script><!--js文件在最后都有哦-->
<script src="https://cdn.jsdelivr.net/npm/echarts-gl/dist/echarts-gl.min.js"></script>
</head>
<body>
<div id="main" class="list-main">
<!-- 为 ECharts 准备一个具备大小（宽高）的 DOM -->
<div id="areaone" style="width: 2000px;height:1000px;"></div>
<script type="text/javascript">
var goodsNamedata = [];//定义数组用来接受后台的数据，数组名随意啦
var salesMountdata = [];
var salesMountdata0 = [];
var url = "Servletselect";
<!--使用ajax动态获取数据，将获取的数据放到数组中-->
$.ajax({
async: false,
type: "GET",
url: url,
dataType: 'json',
contentType: "application/json;charset=UTF-8",
success: function(result){
console.log(result);
for (var i = 0; i < result.length; i++) {
goodsNamedata.push(result[i].day_id);
salesMountdata.push(result[i].round);
salesMountdata0.push(result[i].cnt);
console.log(result[i].cnt)
}
}
});
//下面就是官网的数据了进行一些简单的修改就可以了
var myChartone = echarts.init(document.getElementById('areaone'));
// 指定图表的配置项和数据
var optionone = {
title: {
text: '柱状图'
},
tooltip: {},
legend: {
data: ['sum','mony'],
orient: 'horizontal',
itemGap: 40,
textStyle: {
color: 'red',
fontSize: '20px',
fontWeight: 700
}
},
xAxis: {
data: goodsNamedata//x轴
},
yAxis: {//y轴不用设置（2d）
},
series: [{
name: 'sum',
type: 'bar',
data: salesMountdata//数据
},
{
name: 'mony',
type: 'bar',
data: salesMountdata0//数据
}]
};
myChartone.setOption(optionone);
</script>
</div>
</body>
</html>
线型图：
线型图的话和圆柱图基本没有太大的区别，思路一致！
