javascript - Highcharts - 气泡在不退出图表的情况下失去焦点

问题描述

https://jsfiddle.net/gh/get/library/pure/highcharts/highcharts/tree/master/samples/highcharts/demo/bubble/

Highcharts.chart('container', {

chart: {
    type: 'bubble',
    plotBorderWidth: 1,
    zoomType: 'xy'
},

legend: {
    enabled: false
},

    }]
},

    useHTML: true,
    headerFormat: '<table>',
    pointFormat: '<tr><th colspan="2"><h3>{point.country}</h3></th></tr>' +

        { x: 69.2, y: 57.6, z: 10.4, name: 'IT', country: 'Italy' },
        { x: 68.6, y: 20, z: 16, name: 'RU', country: 'Russia' },
        { x: 65.5, y: 126.4, z: 35.3, name: 'US', country: 'United States' },
        { x: 65.4, y: 50.8, z: 28.5, name: 'HU', country: 'Hungary' },
        { x: 63.4, y: 51.8, z: 15.4, name: 'PT', country: 'Portugal' },
        { x: 64, y: 82.9, z: 31.3, name: 'NZ', country: 'New Zealand' }
    ]
}]

});

当我点击图表中的一个气泡时，焦点指向这个点击的气泡。但除非鼠标光标退出图表，否则我不能丢失它。有没有办法在鼠标没有悬停在那个气泡上后立即重置焦点？

解决方案

您需要将hideDelay工具提示的选项设置为系列0并禁用stickyTracking：

tooltip: {
    ...,
    hideDelay: 0
},

plotOptions: {
    series: {
        stickyTracking: false,
        ...
    }
}

现场演示： https ://jsfiddle.net/BlackLabel/t57cLqrb/
