[Solved]-highchart dateTimeLabelFormats don't work-Highcharts

it doesn't work because you are setting label format for one day interval, while used is week format, see fixed example: http://jsfiddle.net/f2umr/1/

$('#container').highcharts({
    xaxis: {
        type: 'datetime',
        datetimelabelformats: {
            day: '%b %e',
            week: '%b %e'
        }
    },

    series: [{
        data: [29.9, 71.5, 106.4, 129.2, 144.0, 176.0, 135.6, 148.5, 216.4, 194.1, 95.6, 54.4],
        pointstart: date.utc(2010, 0, 1),
        pointinterval: 24 * 3600 * 1000 * 7// one week
    }]
});
