这真的很简单，你只需要在创建图表之前过滤你的JSON数据。一个简化的过程如下：

const receivedData = [{
    name: 'Start prototype',
    start: '2021-04-11',
    end: '2021-04-17'
}, {
    name: 'Test prototype',
    start: '2022-04-11',
    end: '2022-04-17'
}, {
    name: 'Develop',
    start: '2022-06-11',
    end: '2022-07-11'
}, {
    name: 'Run acceptance tests',
    start: '2022-09-11',
    end: '2022-09-21'
}];

const filteredData = receivedData.filter(
    dataEl => new Date(dataEl.start) > new Date('2022')
);

// THE CHART
Highcharts.ganttChart('container', {
    series: [{
        name: 'Project 1',
        data: filteredData.map(({
            name,
            start,
            end
        }) => ({
            name,
            start: new Date(start).getTime(),
            end: new Date(end).getTime()
        }))
    }]
});
