子进度指示器在折叠和展开父元素后不起作用

Question

>start 是测试原型的父级。当我折叠启动原型并展开测试原型的进度指示器时，未在高图甘特图中正确显示。

series: [{
    name: 'Project 1',
    data: [{
        id: 'start',
        name: 'Start prototype',
        start: Date.UTC(2014, 10, 18),
        end: Date.UTC(2014, 10, 25),
        completed: 0.25
    }, {
        id: 'test',
        parent: 'start',
        name: 'Test prototype',
        start: Date.UTC(2014, 10, 27),
        end: Date.UTC(2014, 10, 29),
        completed: 0.35
    }, {
        name: 'Develop',
        start: Date.UTC(2014, 10, 20),
        end: Date.UTC(2014, 10, 25),
        completed: {
            amount: 0.12,
            fill: '#fa0'
        }
    }, {
        name: 'Run acceptance tests',
        start: Date.UTC(2014, 10, 23),
        end: Date.UTC(2014, 10, 26)
    }]
}]

}(;

这是

Highcharts Gantt中的一个错误，报告如下： https://github.com/highcharts/highcharts/issues/10942

作为解决方法，您可以使用以下代码：

Highcharts.addEvent(Highcharts.Axis, 'afterBreaks', function() {
    this.series.forEach(s => s.data.forEach(point => point.graphicOverlay = point.graphicOverlay && point.graphicOverlay.destroy()));
});
