Highcharts in django

本文关键字：django in Highcharts      更新时间：2023-09-26

我是django的新手。我想在django中使用高图来绘制图表。我所做的是创建了一个名为Telecom的项目。然后我把highcharts文件放在Telecom/media/hightcharts文件夹中。我在Telecom/media/js位置写了一个script.js文件。

script.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]
            }]
        });
    });

但是图形没有显示，如何使其工作？

您的程序需要互联网来显示图形，因为.js文件的位置来自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#更新静态根和url

STATIC_ROOT = ''
STATIC_URL = '/static/'

现在将.js（源文件）放在静态文件夹中，该文件夹是在应用程序文件夹中创建的。

现在，在模板中，通过将下面的代码放入header标记来加载.js文件。

{% load staticfiles %}    
    <script src="{% static "js/jquery-1.3.2.min.js" %}"></script>
    <script src="{% static "js/script.js" %}"></script>

在这里，我把示例js库放在像/my_app/static/js/...这样的目录位置，所以在src上，你需要在静态文件夹之后给出位置。希望你在回答完这个问题后能够显示图表。

希望这将对您有所帮助：

import os
BASE_DIR = os.path.dirname(os.path.dirname(__file__))
SETTINGS_FILE_PATH = os.path.realpath(__file__)
SETTINGS_DIR = os.path.dirname(SETTINGS_FILE_PATH)
PROJECT_DIR = os.path.dirname(SETTINGS_DIR)
MEDIA_DIR = os.path.join(PROJECT_DIR, 'media')
STATIC_DIR = os.path.join(PROJECT_DIR, 'static')
STATIC_URL = '/static/'

STATICFILES_DIRS = (
    STATIC_DIR,
)
MEDIA_URL = '/media/'
MEDIA_ROOT = MEDIA_DIR

TEMPLATE_DIRS = (
    os.path.join(PROJECT_DIR, 'templates'),
    )
