无法修改作为全局变量初始化的 highcharts

我在玩highcharts。现在我知道我想要什么了，我试图创建一个简单的逻辑来动态更新数据（xaxis 类别）及其系列。但我被困在基础知识上。我无法从一个简单的函数访问 highchart，尽管它是一个全局变量。


    <script>


        var myChart;

        $(document).ready(function() {

            init();

        });


        function init(){

            myChart = $('#graph-container').highcharts({

                title: {

                    text: 'Dummy Title'

                },

                xAxis: {

                    categories: ['Dummy1', 'Dummy2']

                },

                series: []

            });

        }


        function onclickButton(){

            //myChart.xAxis[0].setCategories(['A','B']);

            myChart.addSeries({

                    name: 'John',

                    data: [['A',1], ['B',2]]

                });

        }

    </script>

</head>

<body>

    <div id="graph-container" style="width:100%; height:400px;"></div>

    <input type="button" value="Click me" onclick="onclickButton()">

</body></html>

它说 xAxis 未定义，或者 addSeries 函数不存在。我究竟做错了什么？
