我正在尝试将数据从我的 mysql 获取到 Highcharts 条形图中。我有来自 mysql 的数据，其中包括端口号和每个端口的平均字节数。这是我的 php 查询和 html 页面的内容。数据（平均字节）很好地显示在图表上。我无法获取要显示的类别（端口）数据。

<?php
$con = mysql_connect("localhost","root","kdkdkdk") or die(mysql_error());
mysql_select_db("silk", $con);

$result = mysql_query("SELECT dstPortNum,avgByte FROM statistic_avgbytesport ORDER BY avgByte DESC LIMIT 10;");

$rows = array();
while($r = mysql_fetch_array($result)) {
    $row[0] = $r[0];
    $row[1] = $r[1];
    array_push($rows,$row);
}

print json_encode($rows, JSON_NUMERIC_CHECK);
#print json_encode($rows[0][0], JSON_NUMERIC_CHECK);

mysql_close($con);
?>

和我的 html 页面来显示图表。

你的数据到底是如何显示的，你没有把 $conn 作为 mysql_query() 的第二个参数；它应该是

$result = mysql_query("SELECT dstPortNum,avgByte FROM statistic_avgbytesport ORDER BY avgByte DESC LIMIT 10;",$conn);

你可以使用这样的东西：

$.getJSON("averageBytesPerPort.php", function(json) {
    var options = {
        chart: {
            renderTo: 'avgbytes'                  
        },

        title: {
            text: 'Average Bytes Per Port'
        },

        pane: {
            size:'80%'
        },

        xAxis: {
            title: {
                text: 'PORTS'
            },
            categories: data.categories
        },

        yAxis: {
            min: 0,
            title: {
                text: 'Bytes'
            }
        },

        series: [{
            type: 'bar',
            name: 'Average Bytes',
            data: data
        }]
    }

    chart = new Highcharts.Chart(options);
});
