因此，我尝试使用 Django 中的 Highcharts 制作烛台图，但无法在网页上显示图表，而是显示所获取数据的 JSON 列表。

我正在使用 iexcloud 的 API 来获取历史数据

这是我的逻辑： 视图.py 文件：

def candlestick_chart_data(request):
    api_key = 'my_api_key'
    stock_data = get_historical_data(
        "AAPL", start="2023-01-01", end="2023-05-05", output_format="pandas", token=api_key)
    stock_data_array = [{
        'x': date.isoformat(),
        'open': row['open'],
        'high': row['high'],
        'low': row['low'],
        'close': row['close']
    } for date, row in stock_data.iterrows()]
    return JsonResponse(stock_data_array, safe=False)

我的模板，即candlestick_chart.html

            });
        }).catch(error => console.error(error.message));
</script>
{% endblock %}

以及我的 url 路径（如果需要）：

path('candlestick-chart-data/', views.candlestick_chart_data, name='candlestick-chart'),

这是我在网页上得到的输出 本地主机网页图像

我尝试将 console.log 语句放入代码中，尝试在终端中打印数据，一切正常，但我无法理解为什么如果一切正常，图表不会出现在网页中
