Highcharts/PHP/JS菜鸟在这里。我在格式化输入Highcharts所需的数据数组($data)时遇到问题。嵌入的php代码输出以下格式的日期时间/十进制数据数组

[1388680500000, 11215], [1388680800000, 11334], [1388681100000, 11487], [1388681400000, 11600], [1388681700000, 11641], [1388682000000, 11648], [1388682300000, 11692], [1388682600000, 11641], [1388682900000, 11715], [1388683200000, 11808], [1388683500000, 11845], [1388683800000, 11813], [1388684100000, 11771], [1388684400000, 11746], [1388684700000, 11808], [1388685000000, 11784], [1388685300000, 11727], [1388685600000, 11608], [1388685900000, 11648], [1388686200000, 11587], [1388686500000, 11555], [1388686800000, 11596], [1388687100000, 11541], [1388687400000, 11441], [1388687700000, 11393], [1388688000000, 11340], [1388688300000, 11152], [1388688600000, 11031], [1388688900000, 10920], [1388689200000, 10681], [1388689500000, 10221], [1388689800000, 9895]

我目前正在将此数据(在[]中)手动复制到series: data: field中，它成功地生成了图表(见下文)。我尝试用序列[{ data：[] ]替换数据字段，但是图表不再创建。(根据http://www.highcharts.com/docs/working-with-data/preprocessing-data-from-a-database)

我还在php和JS中尝试了多次json_encode($data)的迭代，但都无济于事。如果有人能向我展示php输出到Highcharts数据字段的准确翻译，最好是使用JSON，我将非常感激。

我已经将脚本重新调整为以下格式，但是图表根本不再绘制...我确信JSON格式是正确的。请帮帮我！

尝试使用下面的代码从MYSQL获取记录并将其转换为highchart数据。

setup.js

    var chart;
    $(document).ready(function() {
        var cursan = {
            chart: {
                renderTo: 'current_sanand',
                defaultSeriesType: 'area',
                marginRight: 10,
                marginBottom: 20
            },
            title: {
                text: '',
            },
            subtitle: {
                text: '2013/14',
            },
            xAxis: {
                categories: ['Apr', 'May', 'Jun', 'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec', 'Jan', 'Feb', 'Mar']
            },
            yAxis: {
                title: {
                    text: 'Amount [Billion]'
                },
                plotLines: [{
                    value: 0,
                    width: 1,
                    color: '#808080'
                }]
            },
            tooltip: {
                crosshairs: true,
                shared: true
            },
            legend: {
                layout: 'vertical',
                backgroundColor: 'white',
                align: 'right',
                verticalAlign: 'top',
                y: 35,
                x: -10,
                borderWidth: 1,
                borderRadius: 0,
                title: {
                    text: '::::::::::::'
                },
                floating: true,
                draggable: true,
                zIndex: 20

            },

            plotOptions: {

                series: {
                    cursor: 'pointer',  
                    marker: {
                        lineWidth: 1
                    }
                }
            },

            series: [{
                color: Highcharts.getOptions().colors[2],
                name: 'Sanand',
                marker: {
                    fillColor: '#FFFFFF',
                    lineWidth: 2,
                    lineColor: null // inherit from series
                },
                dataLabels: {
                    enabled: true,
                    rotation: 0,
                    color: '#666666',
                    align: 'top',
                    x: -10,
                    y: -10,
                    style: {
                        fontSize: '9px',
                        fontFamily: 'Verdana, sans-serif',
                        textShadow: '0 0 0px black'
                    }
                }
            }],

      }


     $.getJSON("data.php", function(json){
            options.xAxis.categories = json['category'];
            options.series[0].name = json['name'];
            options.series[0].data = json['data'];
            chart = new Highcharts.Chart(options);
     });

});

data.php

$con =mysql_connect(“本地主机”，“根”，"")；

    if (!$con) {
      die('Could not connect: ' . mysql_error());
    }

    mysql_select_db("test", $con);
    $sql = mysql_query("SELECT unix_timestamp(DATETIMES), TEST FROM PT");
    $result['name'] = 'Sales Summary';
    while($r = mysql_fetch_array($sql)) {
    $datetime = $r['inv_dt'];
    $result['category'][] = $datetime;
    $result['data'][] = round($r['amount'],2) ;
}
print json_encode($result);

index.php

 <html>
    <body>
       <div id="container" style="height: 300px"></div>
    </body>
 </html>

我尽了最大的努力，这个方法工作正常。试试看。
