我有一个问题,我只能在我的网络上加载1个zingchart,即使我有2个图表的代码.
代码将生成最新的图表,在这种情况下,饼图并忽略条形图.
以下是我的代码

<?php
//getDBConnect function
require 'dbconnect.php';

//Get ID from form 
$id = $_GET['staffid'];

//connect to database
$con = getDBConnect();

if(!mysqli_connect_errno($con)){
$sqlQueryStr = 
        "SELECT a.ai_Name, r.duration " .
        "FROM report AS r, academicinstitution AS a " . 
        "WHERE r.ai_Id = a.ai_Id ";

$result = mysqli_query($con,$sqlQueryStr);

mysqli_close($con);
} else {
    echo "Failed to connect to MySQL: " . mysqli_connect_error();
}

//Get data into array
$emparray = array();
while ($row = mysqli_fetch_assoc($result)) {
    $emparray[] = $row;
}

//Group array by ai_Name …
