Question

我有一个条形图的代码，它运行良好，但这段代码有静态值，但我想从服务器获取值，每次都有不同的图表（我的意思是我不想给出任何值代码）。我怎么能这样做？这是代码：

<script src="http://code.jquery.com/jquery-1.9.1.js"></script>
<script src="http://code.jquery.com/jquery-migrate-1.1.0.js"></script>

<script src="https://code.highcharts.com/highcharts.js"></script>
<script src="https://code.highcharts.com/modules/exporting.js"></script>

<div id="container" style="min-width: 310px; max-width: 800px; height: 400px; margin: 0 auto"></div>

<script>


$(function () {
    $('#container').highcharts({
        chart: {
            type: 'bar'
        },
        title: {
            text: 'Top 10 HashTags'
        },

        xAxis: {
            categories: ['Africa', 'America', 'Asia', 'Europe', 'Oceania'],
            title: {
                text: null
            }
        },
        yAxis: {
            min: 0,
            title: {
                text: 'Number of repeated hashTags ',
                align: 'high'
            },
            labels: {
                overflow: 'justify'
            }
        },
        tooltip: {
            valueSuffix: ' millions'
        },
        plotOptions: {
            bar: {
                dataLabels: {
                    enabled: true
                }
            }
        },
        legend: {
            layout: 'vertical',
            align: 'right',
            verticalAlign: 'top',
            x: -40,
            y: 80,
            floating: true,
            borderWidth: 1,
            backgroundColor: ((Highcharts.theme && Highcharts.theme.legendBackgroundColor) || '#FFFFFF'),
            shadow: true
        },
        credits: {
            enabled: false
        },
        series: [ {
            name: 'Year 2012',
            data: [1052, 954, 4250, 740, 38]
        }]
    });
});

</script>

给你一个小例子。第一列是xAxis，其他是系列。我希望这对你有帮助。：

<?php
$sql5 = mysqli_query($bd,'SELECT tx_rend_escolas.ano, tx_rend_escolas.ap_med, tx_rend_escolas.rep_med, tx_rend_escolas.abd_med FROM tx_rend_escolas WHERE tx_rend_escolas.fk_cod_entidade = 21438200 ORDER BY tx_rend_escolas.ano ASC;') or die(mysqli_error());
$linhas5 = mysqli_num_rows($sql5);
$proc4 = array();
$proc5 = array();
$proc6 = array();
$proc7 = array();
while ($docs = mysqli_fetch_assoc($sql5)) {
        $proc4[] = "'".$docs['ano']."'";
        $proc5[] = $docs['ap_med'];
        $proc6[] = $docs['rep_med'];
        $proc7[] = $docs['abd_med'];
}
$proc4 = implode(",", $proc4);
$proc5 = implode(",", $proc5);
$proc6 = implode(",", $proc6);
$proc7 = implode(",", $proc7);
?>
