项目中需要绘制饼图,因此简单学习了下echarts的基本使用。
head中引入js文件:
<script src="/static/frame/echarts/echarts.min.js"></script>
body中(圆饼图):
... <div class="card_style layui-col-md5"> <div class="layui-card"> <div id="pie_echarts" class="layui-card-body" style=" 100%;height:170%;"> </div> </div> </div> ...
body中(横向柱状图):
...
<div class="row"> <div id="main"></div> </div>
...
js中:
// 圆饼图
// 基于准备好的dom,初始化echarts实例 var myChart = echarts.init(document.getElementById('pie_echarts')); // 指定图表的配置项和数据 option = { title: { text: 'bug分布', x: 'left' }, tooltip: { trigger: 'item', formatter: "{a} <br/>{b} : {c} ({d}%)" }, color: ['#CD5C5C', '#00CED1', '#9ACD32', '#FFC0CB'], stillShowZeroSum: false, series: [ { name: 'bug分布', type: 'pie', radius: '80%', center: ['60%', '60%'], data: [ {value: 1, name: '后台_bug'}, {value: 3, name: 'IOS_bug'}, {value: 7, name: 'Android_bug'}, {value: 4, name: 'H5_bug'}, ], itemStyle: { emphasis: { shadowBlur: 10, shadowOffsetX: 0, shadowColor: 'rgba(128, 128, 128, 0.5)' } } } ] }; // 使用刚指定的配置项和数据显示图表。 myChart.setOption(option);
// 横向柱状图 var Chart = echarts.init(document.getElementById('main')); Chart.setOption({ title: { text: '预测类别及概率', }, tooltip: { trigger: 'axis', axisPointer: { type: 'shadow' } }, legend: {}, grid: { left: '3%', right: '4%', bottom: '3%', containLabel: true }, xAxis: { type: 'value', boundaryGap: [0, 0.01] }, yAxis: { type: 'category',
// data为横坐标数据 data: [class_name[2], class_name[1], class_name[0]] }, series: [{ type: 'bar', itemStyle: { normal: { color: new echarts.graphic.LinearGradient(0, 0, 0, 1, [{ offset: 0, color: '#fff' }, { offset: 1, color: '#3fa7dc' }]), } },
// data为纵坐标数据 data: [returned_probability[2], returned_probability[1], returned_probability[0]] } ] });
