Question

有人可以帮我这个吗？我正在尝试创建高级图表。我尝试使用mysql和php填充我的图表，但是当我尝试运行它时，会出现图表x轴值，但不会出现y轴值，。任何人都可以为这些问题提供任何解决方案吗？

我的代码在下面给出

<?php
    error_reporting(0);
    $con = @mysql_connect("localhost","root","");

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

    mysql_select_db("bfsdemo", $con);

    $SQL1 =     "SELECT * FROM highcharts_php";

    $result1 = mysql_query($SQL1);

    $data1 = array();
    $data2 = array();

    while ($row = mysql_fetch_array($result1)) {
        $data2[] = $row['visits'];
        $data1[] = $row['timespan'];
    }
    ?>
