Highcharts 上下文菜单按钮在同一图表中出现三次

I am creating a highcharts. But when the chart finishes loading, i can see 3 buttons for context menu and only one of them functional. Please look at the image:

我刚刚在 html 中包含了这些脚本标签：

src =“http://code.highcharts.com/highcharts.js”

src =“http://code.highcharts.com/modules/exporting.js”

尝试添加导出选项：

var chart1 = new Highcharts.Chart({
    chart: {
        // ...
    },
    exporting: {
        buttons: {
            contextButtons: {
                enabled: false,
                menuItems: null
            }
        },
        enabled: true
    },
    // ...

到您的图表选项。看来它可以解决你的问题。

编辑：我只是编辑代码，试试吧。
