I am using jquery widget for displaying a line graph for my file. for this purpose i have 3 files connect.php where i just have my username and password and dbhost name and rest of the two files are here
I am using this code as my data.php
<?php
include 'conn.php';
$conn = oci_connect($dbuser, $dbpass, $dbhost) or die('Error connecting to mysql');
$query = "SELECT PRODUCT, sum(QUANTITY) as QUANTITY FROM SALES GROUP BY PRODUCT";
$resultb = oci_parse($conn, $query);
oci_execute($resultb);
$orders = array();
$i = 0;
while (($row = oci_fetch_array($resultb, OCI_NUM)) != false) {
$orders[] = array(
'ProductName' => $row[0],
'Quantity' => $row[1]
);
}
$_SESSION['orders'] = $orders;
echo json_encode($orders);
?>
and this is my code of file which I want to run

Although my data.php is working fine
Remove "Hello World" from your data.php file, your chart cannot read the array properly because of it

I am new to web programming, I have personal project to track expenditure.
Straight to the point, I have database data contains this month and last month total expenditure. I am able to show it manually (by echo). But i can't pass the value to highcharts series. Due to many small separate data, i want to populate it manually using php/mysql rather than json.
Graph2.php
<?php
$mysql_hostname = "localhost";
$mysql_user = "root";
$mysql_password = "mypassword";
$mysql_database = "mytraining";
$bd = mysqli_connect($mysql_hostname, $mysql_user, $mysql_password, $mysql_database);
if (mysqli_connect_errno()) {
printf("Connect failed: %s\n", mysqli_connect_error());
exit();
}
$query2 = "select year(date) as y, month(date) as m, sum(amount) as p from expenditure_bak group by year(date), month(date) order by m ASC";
$sth = mysqli_query($bd, $query2);
$rows = array();
$rows['name'] = 'Revenue';
while($r = mysqli_fetch_array($sth)) {
$rows['data'][]= round($r['p'],2);
}
//echo join($rows['data'], ','); //able to display correct value 660.2,60
?>

So, what is the correct code to be put inside data: [] in the highcharts series.
Output should be like JSFiddle but using dynamic data from database obviously.
Finally, I want to display something like
Expenditure Tracking
You will likely need to encode your data. I recommend that you take a look at the answer from here Pass a PHP array to a JavaScript function. Based on this, you should be able to do something like this:
JSON.parse(<?php echo json_encode(join($rows[data], ',')) ?>);
then you should be able to get the result that you want. You might not need the JSON.parse.
I have a records.values table in myDB.When new data is inserted into this table I want to change the graph.I used php and highchart but there is nothing can be seen from browser.What is wrong thing in my code.I use ubuntu 14.04.

What is the missing point in here? **I just started to learn php and highcharts. Thank you..
I am getting temperature from MySQL DB and Now I want to plot graph for the same over last 3 days. But the graph doesnt get plotted .
Here is the code for two files.
//Sql.php
<?php
// if you want to send request from a html file stored
// locally uncomment the line below
header('Access-Control-Allow-Origin: *');
// in the commands "mysql_..." change the following:
// xxxx - your SQL server address (np: www.abc.com)
// yyyy - user name
// zzzz - password
// qqqq - database name
// watch out for the capital letters!
mysql_connect("192.168.100.107:3306", "root", "hannan786") or die(mysql_error());
mysql_select_db("pi") or die(mysql_error());
// describe the date ragne - here: the last 3 days
$phpdate=time()- (3*24 * 60 * 60);
$datefrom = date( 'Y-m-d H:i:s', $phpdate );
$dateto = date( 'Y-m-d H:i:s', time() );
$data = mysql_query("SELECT * FROM temp WHERE `time` > '$datefrom'
AND `time` < '$dateto' ORDER BY time ASC") or die(mysql_error());
$rowcount = mysql_num_rows($data);
$counter=1;
// prepare the answer needed by Highcharts:
echo '{
"title": {"text": "temperature"},
"chart": {"renderTo": "container"},
"series": [{"name": "temperature", "data":[';
// fill the data from the database,
// here - the data of interest is stored in column "Temp4":
while($r = mysql_fetch_assoc($data)) {
echo '['.strtotime($r["time"])*1000 . ', '.$r["temperature"]/10 .']';
if($counter < $rowcount){
echo ", ";
}
$counter=$counter+1;
}
// finalize the answer
echo' ]}]}';
mysql_free_result($data);
?>

The charts are using HighChart Library. Please help me out if you have any idea , Why the graph or chart isint working properly.
Thank You .
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
