Somebody can help me. I'm new in php and highcharts. I tried to populate my chart using mysql and php, but when I tried to run it, the chart didn't appear, I only sse a blank web page. And there's no error appeared.
Her's my codes (sorry for messy code):

}
?>
<script type="text/javascript">

And here's my config.php
<?php
$mysql_hostname = "localhost";
$mysql_user = "root";
$mysql_password = "";
$mysql_database = "pos";
$prefix = "";
$bd = mysql_connect($mysql_hostname, $mysql_user, $mysql_password) or die("Could not connect database");
mysql_select_db($mysql_database, $bd) or die("Could not select database");
?>
Blank pages usually mean syntax errors. You should switch error_reporting on.
The errors are in the use of your echo statements where you construct the json. The error is that you are missing semi colons in both the echo statements.
Replace <?php echo join($data1, ',') ?> with <?php echo join($data1, ','); ?>
Similarly for $data2:
Replace <?php echo join($data2, ',') ?> with <?php echo join($data2, ','); ?>
Another improvement you could make in the following block:
<?php
include "config.php";
$SQL1 = "SELECT * FROM pos";
$result1 = mysql_query($SQL1);
$data1 = array();
while ($row = mysql_fetch_array($result1)) {
$data1[] = $row['name'];
}
$result2 = mysql_query($SQL1);
$data2 = array();
while ($row = mysql_fetch_array($result2)) {
$data2[] = $row['Qty'];
}
?>
Instead of executing query twice to build two arrays, you could get rid of one of the queries and build both the arrays from the same query result:
<?php
include "config.php";
$SQL1 = "SELECT * FROM pos";
$result1 = mysql_query($SQL1);
$data1 = array();
$data2 = array();
while ($row = mysql_fetch_array($result1)) {
$data1[] = $row['name'];
$data2[] = $row['Qty'];
}
?>
Note: The php mysql extension is deprecated as of PHP 5.5.0, you should be using either MySQLi or PDO_MySQL.
Please Try Example as below. I think it can help you
SQL Table
CREATE TABLE IF NOT EXISTS `sales` (
`id` int(11) NOT NULL AUTO_INCREMENT,
`month` varchar(200) DEFAULT NULL,
`amount` varchar(11) DEFAULT NULL,
PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=latin1 AUTO_INCREMENT=118 ;
INSERT INTO `sales` (`id`, `month`, `amount`) VALUES
(24, 'Apr', '15'),
(25, 'May', '40'),
(26, 'Jun', '26'),
(27, 'Jul', '31'),
(28, 'Aug', '39'),
(29, 'Sep', '25'),

s will import data from mysql from data.php and add to chart which is create previously in js.
data.php
$con=mysql_connect('localhost','root','');
mysql_select_db("test", $con);
$result=mysql_query('select * from sales order by id');
while($row = mysql_fetch_array($result)) {
echo $row['month'] . "\t" . $row['amount']. "\n";
}
our chart is fully loaded .with mysql records and output will look li below
Output
its example of area chart, you can change type of chart by changing defaultSeriesType: 'area'
Click Here for more Example with source.
I think your supposed to have single quotes around this
categories: [<?php echo join($data1, ',') ?>],
Should be
categories: ['<?php echo join($data1, ',') ?>'],
Even if this is an old thread, this might have nothing to do with Highcharts, I'v just noted the final phrase in your error message:
"...Warning: mysql_fetch_array() expects parameter 1 to be resource, boolean given
in C:\xampp\htdocs\otrs\chart\graphs\pos\index.php on line 22"
tipically has to do with a query that fails returning FALSE instead of a rowset. You should take a look at this related question.

The JSON string is produced using the file
data.php:
<?php
$con = mysql_connect("*****", "*****", "*****");
if (!$con) {
die('Could not connect: ' . mysql_error());
}
mysql_select_db("*****", $con);
$sth = mysql_query("SELECT revenue FROM projections_sample");
$rows = array();
$rows['name'] = 'Revenue';
while ($r = mysql_fetch_array($sth)) {
$rows['data'][] = $r['revenue'];
}
$sth = mysql_query("SELECT overhead FROM projections_sample");
$rows1 = array();
$rows1['name'] = 'Overhead';
while ($rr = mysql_fetch_assoc($sth)) {
$rows1['data'][] = $rr['overhead'];
}
$result = array();
array_push($result, $rows);
array_push($result, $rows1);
print json_encode($result, JSON_NUMERIC_CHECK);
mysql_close($con);
?>
If I enter a JSON string manually into data.php the charts is displayed as expected.
[{
"name": "Revenue",
"data": [23987, 24784, 25899, 25569, 25897, 25668, 24114, 23899, 24987, 25111, 25899, 23221]

}]
I'm assuming my connection details are correct, because if I purposely enter the wrong password I get the MySQL connection error...
“Could not connect: Access denied for user ‘*****’#'localhost’ (using password: YES)”
Also, I get “True” returned when I add “echo #mysql_ping() ? ‘true’ : ‘false’;” to the bottom of the page.
Because I'm convinced it should be working I'm wondering if there is anything related to server configuration that could be preventing me from using JSON?
if you can't use JSON_NUMERIC_CHECK (because it requires PHP 5.3.3 (json.constants))
you can cast to int [$number = (int)"1234";]
in
while ($r = mysql_fetch_array($sth)) {
$rows['data'][] = (int)$r['revenue']; // <- (int)
}
and
while ($rr = mysql_fetch_assoc($sth)) {
$rows1['data'][] = (int)$rr['overhead']; // <- (int)
}
than
print json_encode($result);
Hello I try to use Highcharts with data's from an sql Database by using json.
There are all doing but I can't see any values
I get the Data's with this script:
<?php
header('content-type: text/html; charset=utf-8');
include("db.inc.php");
$con = mysql_connect(DB_SERVER, DB_USER, DB_PASSWOR
if (!$con) {
die('Could not connect: ' . mysql_error());
}
mysql_select_db(DB_NAME, $con);
$sth0 = mysql_query("SELECT `DATETIME` FROM `dg_wall24` WHERE DATETIME >
NOW()INTERVAL 1 HOUR");
$rows0 = array();
$rows0['name'] = 'DATETIME';
while($r0 = mysql_fetch_array($sth0)) {
$rows0['data'][] = $r0['DATETIME'];
}
$sth1 = mysql_query("SELECT `dg_t01` FROM `dg_wall24` WHERE DATETIME >
NOW()INTERVAL 1 HOUR");
$rows1 = array();
$rows1['name'] = 'dg_t01';
while($r1 = mysql_fetch_array($sth1)) {
$rows1['data'][] = $r1['dg_t01'];
}
$sth2 = mysql_query("SELECT `dg_h01` FROM `dg_wall24` WHERE DATETIME >
NOW() INTERVAL 1 HOUR");
$rows2 = array();
$rows2['name'] = 'dg_h01';
while($r2 = mysql_fetch_array($sth2)) {
$rows2['data'][] = $r2['dg_h01'];
}
$result = array();
array_push($result,$rows0);
array_push($result,$rows1);
array_push($result,$rows2);
print json_encode($result);
mysql_close($con);
?>
The Result:
[{"name":"DATETIME","data":["2013-04-27 08:17:52","2013-04-27 08:22:52","2013-04-27 08:27:53","2013-04-27 08:32:54","2013-04-27 08:37:55","2013-04-27 08:42:55","2013-04-27 08:47:56","2013-04-27 08:52:57","2013-04-27 08:57:58","2013-04-27 09:02:58","2013-04-27 09:07:59","2013-04-27 09:13:00"]},{"name":"dg_t01","data":["22.40","22.40","22.40","22.40","22.30","22.30","22.40","22.40","22.40","22.40","22.40","22.40"]},{"name":"dg_h01","data":["40.20","40.40","40.50","40.80","40.70","40.70","40.80","40.90","41.00","41.00","40.90","40.70"]}]
In the Highchart I can See the timeline on the x Axis and the name of the values but no line and no values.

It is possible that I have an problem with the Dataformat (float, int...) or with the Point in the values?
Many thanks for the help
The problem is indeed that your JSON object contains String values instead of Float values for your data:
{ ... "data":["40.20","40.40","40.50", ... ]}
I don't know what the field type in your database is, and I'm no PHP coder, but you could try setting the JSON_NUMERIC_CHECK option on json_encode.
If that doesn't work for you, you could also convert the Strings using parseFloat in Javascript:
for (var i = 0, num; num = json[1].data[i]; i++)
{
json[1].data[i] = parseFloat(num);
}
See my example on Fiddle.

Hi guys, I dont kwno where I have a mistake, could you help me please? On X-axis should be the datetime from column CAS-> it works but it doesnt display column PARS_DATA. Thanks for your help, thanks.
MySQL TABLE screen:
Chart which I see:
You should convert your date time field to unix timestamp for process on it.
so strtotime function is good idea.
In your code, follow this :
$result=mysql_query($sql)or die(mysql_error());
if(mysql_num_rows($result)>0){
while($row=mysql_fetch_array($result))
{
$uts=strtotime($row['time']); //convert to Unix Timestamp
$date=date("l, F j, Y H:i:s",$uts); //standard template for draw chart
echo $date . "\t" . $row['new_cost']. "\n"; //only this template work
}
$sql: your sql query text.
$result: feedback.
$row['new_cost']: my field for cost.
for more details, follow this link
good luck
is anyone ever use hightchart??i want to use hightchart to represent the data retrieve from mysql database..i try look at the example,this is full example:

// As we're loading the data asynchronously, we don't know what order it will arrive. So

the problem is they used this link ("http://www.highcharts.com/samples/data/jsonp.php?filename='+ name.toLowerCase() +'-c.json&callback=?") to get the data and which that i cant to view the example how they display the data..
i dont know how the link "http://www.highcharts.com/samples/data/jsonp.php" is look like, and how they represent the data.. i want to make my own page that retrieve data from database and replace the link above with my own php page..
this is working example...http://www.highcharts.com/stock/demo/compare
You have to create an array of data you want to populate. Then encode the php array to json format using json_encode. Echo that json string.
Here is a sample code
$a[] = 1133740800000;
$a[] = 1133740800000;
$a[] = 1133740800000;
$a[] = 1133740800000;
$a[] = 1133740800000;
$b[] = 405.85;
$b[] = 405.85;
$b[] = 405.85;
$b[] = 405.85;
$b[] = 405.85;
foreach($a as $i => $v)
{
$cordinates[]= array($v,$b[$i]);
}
echo (json_encode($cordinates));
Hope this helps.

Using firebug, you can check the response of the ajax, should be a json object
