You need to set the xAxis min and max, to show a specific area on chart load. Can be done like this:

xAxis: {
  min: 1330764400000,
  max: 1330774400000
},


$.getJSON('https://cdn.rawgit.com/highcharts/highcharts/057b672172ccc6c08fe7dbb27fc17ebca3f5b770/samples/data/large-dataset.json', function (data) {

    // Create a timer
    var start = +new Date();

    // Create the chart
    Highcharts.stockChart('container', {
        chart: {
            events: {
                load: function () {
                    if (!window.TestController) {
                        this.setTitle(null, {
                            text: 'Built chart in ' + (new Date() - start) + 'ms'
                        });
                    }
                }
            },
            zoomType: 'x'
        },

        rangeSelector: {

            buttons: [{
                type: 'day',
                count: 3,
                text: '3d'
            }, {
                type: 'week',
                count: 1,
                text: '1w'
            }, {
                type: 'month',
                count: 1,
                text: '1m'
            }, {
                type: 'month',
                count: 6,
                text: '6m'
            }, {
                type: 'year',
                count: 1,
                text: '1y'
            }, {
                type: 'all',
                text: 'All'
            }],
            selected: 3
        },

        yAxis: {
            title: {
                text: 'Temperature (°C)'
            }
        },
        xAxis: {
            min: 1330764400000,
          max: 1330774400000
        },

        title: {
            text: 'Hourly temperatures in Vik i Sogn, Norway, 2009-2017'
        },

        subtitle: {
            text: 'Built chart in ...' // dummy text to reserve space for dynamic subtitle
        },

        series: [{
            name: 'Temperature',
            data: data.data,
            pointStart: data.pointStart,
            pointInterval: data.pointInterval,
            tooltip: {
                valueDecimals: 1,
                valueSuffix: '°C'
            }
        }]

    });
});

If you want to show a specific area after the chart has been drawn, you can use the setExtremes function like this:

chart.xAxis[0].setExtremes(1330764400000, 1330774400000, true);

API Reference: Axis.setExtremes()

$.getJSON('https://cdn.rawgit.com/highcharts/highcharts/057b672172ccc6c08fe7dbb27fc17ebca3f5b770/samples/data/large-dataset.json', function (data) {

    // Create a timer
    var start = +new Date();

    // Create the chart
    Highcharts.stockChart('container', {
        chart: {
            events: {
                load: function () {
                    if (!window.TestController) {
                        this.setTitle(null, {
                            text: 'Built chart in ' + (new Date() - start) + 'ms'
                        });
                    }
                }
            },
            zoomType: 'x'
        },

        rangeSelector: {

            buttons: [{
