Question

我正在尝试将我的mysql中的数据导入Highcharts条形图。我有来自mysql的数据，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。数据（平均字节数）显示在图表上就好了。我无法显示要显示的类别（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);
?>

我的html页面显示图表。

Answer 1

您可以使用以下内容：

$.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);
});

Answer 2

你的数据如何显示在地球上，你没有把$ conn作为第二个参数的mysql_query（）; 它应该是

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