javascript - 如何从外部调用 highcharts 按钮

Question

我有一个简单的 highcharts，其中包含一个自定义按钮，但在这里我需要从 highcharts 中初始化该按钮，以便每当我单击它时，它不应该隐藏，只有图表应该隐藏。下面是我的代码，任何人都可以帮我吗？我已经更新了这个插件中的代码 http://plnkr.co/edit/YSLQMoQpKZqFPk0PXhXm?p=preview

}

    }

$("#myDiamondButton").click(function(){
    $('#container').hide();

要实现这一点，请创建您希望保留在页面上的按钮作为图表范围之外的单独元素。从图表中删除“导出”选项，然后为按钮创建一个新的 HTML 元素。

Highcharts.chart('container', {

    title: {
        text: 'Solar Employment Growth by Sector, 2010-2016'
    },

    subtitle: {
        text: 'Source: thesolarfoundation.com'
    },

    yAxis: {
        title: {
            text: 'Number of Employees'
        }
    },
    legend: {
        layout: 'vertical',
        align: 'right',
        verticalAlign: 'middle'
    },

    plotOptions: {
        series: {
            label: {
                connectorAllowed: false
            },
            pointStart: 2010
        }
    },

    series: [{
        name: 'Installation',
        data: [43934, 52503, 57177, 69658, 97031, 119931, 137133, 154175]
    }],

    responsive: {
        rules: [{
            condition: {
                maxWidth: 500
            },
            chartOptions: {
                legend: {
                    layout: 'horizontal',
                    align: 'center',
                    verticalAlign: 'bottom'
                }
            }
        }]
    }

});
$("#myDiamondButton").click(function(){
    $('#container').hide();
});
