HI EE,

i'm trying to build a json array from the data below to fit an json array for Highchart

I've been grabbing the sql using php like so


<?php
/* Set Connection Credentials */
$server="---------";
$database="-----------";
$user="----------";

$password="----------------";
 
/* Connect using SQL Server Authentication. */
$connection = odbc_connect("Driver={SQL Server Native Client 10.0};Server=$server;Database=$database;", $user, $password);
if (!$connection) {
  die("Failed");
}

 
/* TSQL Query */
$query = "Select * from data";

$result = odbc_exec($connection,$query);
if (!$result) {
  die("Invalid query");
}


/* Process results */
$json = array();
 
     while ($row = odbc_fetch_array($result)) {
    $json = 
array(
$row['JAN'],
$row['FEB'],
$row['MAR'],
$row['APR'],
$row['MAY'],
$row['JUN'],
$row['JUL'],
$row['AUG'],
$row['SEP'],
$row['OCT'],
$row['NOV'],
$row['DEC']
);
}

echo json_encode($json,JSON_NUMERIC_CHECK );
$jsonData = json_encode($json,JSON_NUMERIC_CHECK );


 

Open in new window


then pass it to javascript via
var jsonData = <?php echo $jsonData ?>;

http://jsfiddle.net/gh/get/jquery/1.9.1/highslide-software/highcharts.com/tree/master/samples/highcharts/demo/column-basic/

if you have a look at the jsfiddle example the array they accept is like:

series: [ {name: , data: },{name: , data: },{name: , data: } ]

http://sqlfiddle.com/#!3/d7917/1

I've managed to get the query coming into an array.... but just not in the right format accepted.

CREATE TABLE Data
(
[Name]                  varchar(50),
[year]				    int ,
[JAN]					decimal(18,2),
[FEB]					decimal(18,2),
[MAR]					decimal(18,2),
[APR]					decimal(18,2),
[MAY]					decimal(18,2),
[JUN]					decimal(18,2),
[JUL]					decimal(18,2),
[AUG]					decimal(18,2),

[OCT]					decimal(18,2),
