I decided to make a graph with the help of here on LAN everything works well, but when I upload it to the server, there is nothing, although it should be. What could be the problem?
html template

{% extends 'main/base.html' %}
{% block content %}
{% load static %}
<html>
    <head>
        <title>django-chartjs line chart demo</title>
        <!--[if lte IE 8]>
            <script src="{% static 'js/excanvas.js' %}"></script>
        <![endif]-->
    </head>
    <body>
        <h1>Статистика продаж</h1>

        <canvas id="myChart" width="500" height="500"></canvas>

        <script type="text/javascript" src="http://code.jquery.com/jquery-1.10.0.min.js"></script>
        <script type="text/javascript" src="{% static 'js/Chart.min.js' %}"></script>
        <script type="text/javascript">
            $.get('{% url "line_chart_json" %}', function(data) {
                var ctx = $("#myChart").get(0).getContext("2d");
                new Chart(ctx, {
                    type: 'line', data: data
                });
            });
        </script>
    </body>
</html>
{% endblock %}>

class LineChartJSONView(BaseLineChartView):
    def get_labels(self):

        return ["January", "February", "March", "April", "May", "June", "July"]

        return 


line_chart = TemplateView.as_view(template_name='line_chart.html')
