自动刷新javascript无需加载整个页面

我正在使用highcharts和传单，我希望我的脚本每10秒刷新一次，而不刷新整个页面。我已经成功地用我的highcharts php文件这样做了，但是当我用我的传单脚本做同样的事情时，什么也没有发生，地图没有出现。我认为问题出在函数的使用上，但为什么它对高图有效，而对传单却不行呢?

highcharts php文件代码

<div id="nb_tweets" style="width:100%; height:400px;"></div>
<script>
    $(function myFunction() 
    {
        <?php include 'import_nb_tweets.php'; ?>
        <?php include 'import_nb_users.php'; ?>
        $('#nb_tweets').highcharts(
        {
            chart: 
            {
                type: 'line'
            },
            title: 
            {
                text: 'Number of tweets trend'
            },
            xAxis: 
            {
                categories: x_axis
            },
            yAxis: 
            {
                title: 
                {
                    text: 'Number of tweets'
                }
            },
            series: 
            [
                {
                    name: 'Precise geolocation',
                    data: nb_precise
                }
                , 
                {
                    name: 'Associated geolocation',
                    data: nb_associated
                }, 
                {
                    name: 'All tweets',
                    data: nb_total
                }
            ]
        });
        setTimeout(myFunction, 10000);
    });
</script>
