Django - 使用Echarts
about
Echarts
Echarts是一个非常优秀的可视化框架,由百度开源,提供了非常丰富的图表类型。
Github地址:https://github.com/apache/incubator-echarts
官网地址:echartsjs.com/zh/index.html
用过echarts的同学都知道,它提供了一个叫setOptions的方法,通过这个方法我们传入一个options就可以生成一个图表了。
对开发者而言,这是非常方便的,我们只需维护这个options变量就OK了。
pyecharts
pyecharts是一款将echarts封装到python中的一款开源框架,由国内几个大哥写的,源码拜读了些许,感觉封装的很有层次感,pythonic十足。

示例
在视图函数中处理好相关数据:
from django.shortcuts import render, redirect, HttpResponse
from django.http import JsonResponse
def test(request):
if request.method == "POST":
obj = ([{\'value\': 3, \'name\': \'未执行\'}, {\'value\': 8, \'name\': \'已执行\'}], [\'未执行\', \'已执行\'])
bar = [120, 200, 150, 80, 70, 110, 130]
return JsonResponse({"obj": obj, \'bar\': bar})
else:
return render(request, \'test.html\', )
然后前端调用:
<!DOCTYPE html>
<html lang="en">
<head>
{% load static %}
<meta charset="UTF-8">
<meta http-equiv="x-ua-compatible" content="IE=edge">
<meta name="viewport" content="width=device-width, initial-scale=1">
<title>Title</title>
</head>
<body>
<div id="Pie1" style="width: 400px;height:300px;"></div>
<div id="barSimple" style="width: 400px;height:300px;"></div>
</body>
<script src="https://cdn.bootcss.com/jquery/2.2.4/jquery.min.js"></script>
<script src="https://cdn.bootcss.com/echarts/3.0.0/echarts.min.js"></script>
<script>
// 饼图
function Pie1(data, ) {
var myChart = echarts.init(document.getElementById(\'Pie1\'));
option = {
title: {
text: \'用例执行状态统计\',
subtext: \'\',
x: \'center\'
},
tooltip: {
trigger: \'item\',
formatter: "{a} <br/>{b} : {c} ({d}%)"
},
legend: {
orient: \'vertical\',
left: \'left\',
data: data[1]
},
series: [
{
name: \'用例执行状态\',
type: \'pie\',
radius: \'55%\',
center: [\'50%\', \'60%\'],
data:data[0],
itemStyle: {
emphasis: {
shadowBlur: 10,
shadowOffsetX: 0,
shadowColor: \'rgba(0, 0, 0, 0.5)\'
}
}
}
]
};
myChart.setOption(option);
}
// 柱状图
function barSimple(data) {
var myChart = echarts.init(document.getElementById(\'barSimple\'));
option = {
xAxis: {
type: \'category\',
data: [\'Mon\', \'Tue\', \'Wed\', \'Thu\', \'Fri\', \'Sat\', \'Sun\']
},
yAxis: {
type: \'value\'
},
series: [{
data: data,
type: \'bar\'
}]
};
myChart.setOption(option)
}
window.onload = function () {
$.ajax({
url: "/test/",
type:"POST",
data: {"k1": "v1"},
success: function (data) {
// 饼图
Pie1(data[\'obj\']);
// 柱状图
barSimple(data[\'bar\']);
console.log(data)
}
})
}
</script>
</html>
