我是 django 的新手。我想在 django 中使用 highcharts 来绘制图表。我所做的是创建了一个名为 Telecom 的项目。然后我将 highcharts 文件放在文件夹 Telecom/media/highcharts 中。我在 Telecom/media/js 位置写了一个文件 script.js。
脚本.js
$(function () {
$('#container').highcharts({
chart: {
type: 'column'
},
title: {
text: 'Monthly Average Rainfall'
},
subtitle: {
text: 'Source: WorldClimate.com'
},
xAxis: {
categories: [
'Jan',
'Feb',
'Mar',
'Apr',
'May',
'Jun',
'Jul',
'Aug',
'Sep',
'Oct',
'Nov',
'Dec'
]
},
yAxis: {
min: 0,
title: {
text: 'Rainfall (mm)'
}
},
tooltip: {
headerFormat: '<span style="font-size:10px">{point.key}</span><table>',
pointFormat: '<tr><td style="color:{series.color};padding:0">{series.name}: </td>' +
'<td style="padding:0"><b>{point.y:.1f} mm</b></td></tr>',
footerFormat: '</table>',
shared: true,
useHTML: true
},
plotOptions: {
column: {
pointPadding: 0.2,
borderWidth: 0
}
},
series: [{
name: 'Tokyo',
data: [49.9, 71.5, 106.4, 129.2, 144.0, 176.0, 135.6, 148.5, 216.4, 194.1, 95.6, 54.4]
}, {
name: 'New York',
data: [83.6, 78.8, 98.5, 93.4, 106.0, 84.5, 105.0, 104.3, 91.2, 83.5, 106.6, 92.3]
}, {
name: 'London',
data: [48.9, 38.8, 39.3, 41.4, 47.0, 48.3, 59.0, 59.6, 52.4, 65.2, 59.3, 51.2]
}, {
name: 'Berlin',
data: [42.4, 33.2, 34.5, 39.7, 52.6, 75.5, 57.4, 60.4, 47.6, 39.1, 46.8, 51.1]
}]
});
});

但是图表没有显示，如何让它工作？
最佳答案
您的程序需要互联网才能显示图形，因为 .js 文件位置来自 url。如果您想离线加载图形，请下载所需的库(js 文件)并进行如下更改。
settings.py #update static root 和 url
STATIC_ROOT = ''
STATIC_URL = '/static/'
现在将您的 .js(源文件)放入在您的应用程序文件夹中创建的静态文件夹中。
现在在模板中加载 .js 文件，方法是将下面的代码放在 header 标签中。
{% load staticfiles %}
<script src="{% static "js/jquery-1.3.2.min.js" %}"></script>
<script src="{% static "js/script.js" %}"></script>
这里我将示例 js 库放在目录位置，如 /my_app/static/js/... 所以在 src 上你需要在静态文件夹之后给出位置。希望您在按照此答案后能够显示图表。
