我希望它在x轴上显示月份的当前年份。看看不同的解决方案，但没有一个帮助。

拜托，看看我哪里出错，因为我还是新手。

非常感谢你的帮助！

如果年份不需要是动态的，您可以使用内置的JavaScript日期对象在图表选项xAxis标题部分插入当前年份：

xAxis: {
    ...
    title: { 
        text: new Date().getFullYear()
    }
    ...
},

如果您需要年份是动态的，那么您可以将它与现有的AJAX调用一起传递。

views.py

class ChartData(APIView):
    def get(self, request, format=None):
    ...
    data = {
        "xAxisTitle": 2017 # assign year here dynamically using method of choice
        ...
    }

chartViewHigh.html

<script>
    ...
    var xAxisTitle = "";
    ...

    $.ajax({
        ...
        success: function (data) {
            ...
            xAxisTitle = data.xAxisTitle;
            ...
    });

    ...

        xAxis: {
        ...
        title: { 
            text: xAxisTitle
        }
        ...
    },
