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 Telecom/media/highcharts 文件夹中。我在 Telecom/media/js 位置编写了一个文件 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，如何使它工作？

您的程序需要互联网来显示图形，因为 .js 文件位置来自 url。如果要离线加载图形，请下载所需的库（js 文件）并进行如下更改。

settings.py #更新静态根目录和url

STATIC_ROOT = ''
STATIC_URL = '/static/'

现在将您的 .js（源文件）放在应用程序文件夹中创建的静态文件夹中。

现在在模板加载.js文件中，将下面的代码放在 header 标记中。

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

在这里，我将示例 js 库放置在目录位置，例如/my_app/static/js/...，在 src 上，您需要在静态文件夹之后提供位置。希望您在遵循此答案后能够显示图表。

希望这会对您有所帮助：

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'),
    )
