項目中需要繪制餅圖,因此簡單學習了下echarts的基本使用。
head中引入js文件:
<script src="/static/frame/echarts/echarts.min.js"></script>
body中(圓餅圖):
...
<div class="card_style layui-col-md5">
<div class="layui-card">
<div id="pie_echarts" class="layui-card-body" style="width: 100%;height:170%;">
</div>
</div>
</div>
...
body中(橫向柱狀圖):
...
<div class="row"> <div id="main"></div> </div>
...
js中:
// 圓餅圖
// 基於准備好的dom,初始化echarts實例 var myChart = echarts.init(document.getElementById('pie_echarts')); // 指定圖表的配置項和數據 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)' } } } ] }; // 使用剛指定的配置項和數據顯示圖表。 myChart.setOption(option);

// 橫向柱狀圖
var Chart = echarts.init(document.getElementById('main'));
Chart.setOption({
title: {
text: '預測類別及概率',
},
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為橫坐標數據
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為縱坐標數據
data: [returned_probability[2], returned_probability[1], returned_probability[0]]
}
]
});
