这是我的第一篇文章，如果我问了很多人已经这样做过的问题，我深表歉意。我在其他帖子中没有看到我需要的答案。

我正在使用 Flot Charts 并有一个 SQL Server 数据库，我有一个 php 文件，它将连接到数据库并以数组的形式返回 sql 中的所有值。

<?php

$server =  "XXXX";
$database = "XXXX";
$user = "ReportsUser";
$pwd = "ReportsUser";
$cnn = odbc_connect("Driver={SQL Server Native Client     10.0};Server=$server;Database=$database;", $user, $pwd);

if(!$cnn)
{
  echo "error in connecting";
}

$sql = odbc_exec($cnn, "
            SELECT Months
        ,Referrals
            ,ProjectedVol
        FROM mis.ReferralsBudgetvsActual
        WHERE Months <= MONTH(GETDATE())
    ");

while($result = odbc_fetch_array($sql))
{
   $allreferrals[] = array($result['Months'],$result['Referrals'],$result['ProjectedVol']);
}
echo json_encode(($allreferrals), JSON_NUMERIC_CHECK);
exit;

?>

这很好用并产生如下数组

[[1,5981,7465],[2,5473,6962],[3,4974,7391],[4,5731,6985],[5,5891,7080],[6,5168,7136],[7,5551,7543],[8,4427,7242],[9,4617,7204],[10,4807,7642]]

现在，当这一切都放在 jquery 文件中时，这就是我最终陷入困境的地方。除了第一个数据列之外，我看不到它在哪里拉回任何其他列，这怎么做？

// document ready function
$(document).ready(function() {  

        var chartColours = ['#88bbc8', '#ed7a53', '#9FC569', '#bbdce3', '#9a3b1b', '#5a8022', '#2c7282'];

        // function for refreshing shiftstats chart  
        make_chart();
        function make_chart() {

            $.ajax({
                cache: 'false',
                type: 'GET',
                dataType: 'json',
                url: "test.php",
                success: function(data) {

                var d1 = data;
                var d2 = data;                    

                //define placeholder class
                var placeholder = $(".shifts-chart");
                //graph options
                var options = {
                        grid: {

您需要更改 php 数组创建以将数据正确格式化为两个系列：

$d1 = array();
$d2 = array();

while($result = odbc_fetch_array($sql))
{
   array_push($d1, array($result['Months'], $result['Referrals']));
   array_push($d2, array($result['Months'], $result['ProjectedVol']));
}

$allreferrals = array($d1, $d2);
echo json_encode(($allreferrals), JSON_NUMERIC_CHECK);

这应该将其作为数组数组返回：

[
  [[1,5981],[2,5473],[3,4974],[4,5731],[5,5891],[6,5168],[7,5551],[8,4427],[9,4617,7204],[10,4807]],
  [[1,7465],[2,6962],[3,7391],[4,6985],[5,7080],[6,7136],[7,7543],[8,7242],[9,7204],[10,7642]] 
]

（希望我的语法正确，我不是 php 的粉丝）

从评论更新

如果要返回一系列系列，最好从 PHP 中返回关联数组：

$allreferrals = array('ref' => array(), 'projVol'=> array());

while($result = odbc_fetch_array($sql))
{
   array_push($allreferrals['ref'], array($result['Months'], $result['Referrals']));
   array_push($allreferrals['projVol'], array($result['Months'], $result['ProjectedVol']));
}

echo json_encode(($allreferrals), JSON_NUMERIC_CHECK);

然后回到javascript：

$.plot(placeholder,
    [{
        label: "Referrals", 
        data: data["ref"]
      },
      {
         label: "ProjectedVol", 
         data: data["projVol"]
      }], 
 options);
