[Solved]-Highstock Single Navigator for multiple Charts-Highcharts

Yes, you need to only connect setting extremes process in charts, for example:

const chart1 = Highcharts.stockChart('container', {
    ...
});

Highcharts.stockChart('container2', {
    ...,
    xAxis: {
        ...,
        events: {
            setExtremes: function(e) {
                chart1.xAxis[0].setExtremes(e.min, e.max, true, false);
            }
        }
    }
});
