Highcharts 无法更改默认范围选择器Highstock

我试图将5M作为我的默认范围选择器，但它似乎一直坚持在选择器上显示“全部”

   rangeSelector: {
            enabled: true,
            buttons: [{
                    count: 2,
                    type: 'minute',
                    text: '2M'
                }, {
                    count: 5,
                    type: 'minute',
                    text: '5M'
                }, {
                    count: 15,
                    type: 'minute',
                    text: '15M'
                }, {
                    count: 30,
                    type: 'minute',
                    text: '30M'
                }, {
                    count: 3,
                    type: 'hour',
                    text: '3H'
                }, {
                    count: 1,
                    type: 'day',
                    text: '1D'
                }, {
                    count: 30,
                    type: 'day',
                    text: '30D'
                }, {
                    type: 'all',
                    text: 'All'
                }],
            selected: 5,
        },

有人能告诉我我的代码哪里出错了吗？

感谢您的帮助。

我已通过添加allbuttonEnabled:true并更改所选：1解决了我的问题。我刚才有点糊涂

   rangeSelector: {
            enabled: true,
            allButtonsEnabled: true,
            buttons: [{
                    count: 2,
                    type: 'minute',
                    text: '2M'
                }, {
                    count: 5,
                    type: 'minute',
                    text: '5M'
                }, {
                    count: 15,
                    type: 'minute',
                    text: '15M'
                }, {
                    count: 30,
                    type: 'minute',
                    text: '30M'
                }, {
                    count: 3,
                    type: 'hour',
                    text: '3H'
                }, {
                    count: 1,
                    type: 'day',
                    text: '1D'
                }, {
                    count: 30,
                    type: 'day',
                    text: '30D'
                }, {
                    type: 'all',
                    text: 'All'
                }],
            selected: 1,
        },

这将使按钮在默认情况下处于启用状态。你有没有检查过缩放是否对它们起作用。你能提供最新的JSFIDLE吗？
