i have to create a single chart showing different series with different type of chart (Ex: one data series with 'areaspline' and one data series with 'column'). I built a db with a lot of data, extracted by sql query into a json file
[
{ "name": "Test", "data": [2.8,2.8,2.8,2.7,2.7,] },
{ "name": "kwc", "data": [10,1,10,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0] }
]
The json file is correct, but if i try to select the series for a chart with the $.each function it doesn't work!
Here's my code

I tryed any kind of option, but anything gone right :(
Any hope to display 1 chart, 2 or more data series and 2 or more type of charts?
Thanks in advance
It looks like your highcharts creation call is within your $.each function. So it will try to create 2 highcharts, but they both will be created in the same div, so you'll only end up with one.
Also, the way you are caculating datalength, it'll be 2. When, it appears, you'd like it to be the length of the actual data (which is different for your different series).
I can't do the getJSON in a jsfiddle, so I'm assuming your PHP code is creating the json object you listed (and it looks like it would). You can lose the each loop alltogether and set your 2 series like this:
series: [{
name: 'Misure',
color: '#4572A7',
type: 'column',
yAxis: 1,
data: json[1].data,
tooltip: {
valueSuffix: ' Kw'
}
}, {
name: 'Temperature',
color: '#89A54E',
type: 'spline',
data: json[0].data,
tooltip: {
valueSuffix: '°C'
}
}]

Firstly I apologise, I am not a programmer (but I am learning - slowly). I am interested in graphs for Horticultural applications. I have a database that gets data from sensors on an hourly basis and the query grabs the last 12 to 48 readings, according to the select statement. With help from your forum, I have created 3 files that together extract the data from MySQL to plot a graph with multiple series of: Timestamp (with various options for display), temperature and humidity.
I based my work on this example in fiddle https://jsfiddle.net/gh/get/library/pure/highcharts/highcharts/tree/master/samples/highcharts/demo/line-basic which uses data provided 'in the script' but after three weeks I can't inject the data from JSON
The first of my files makes the MySQL db connection, the second file extracts and formats the data into JSON data and the third is supposed to create the graph but doesn't :-(.
this is what is produced with a series label for each row, rather than a line for each series.
Can you help me? I would like a line graphs showing temperature and humidity. Time/date along the bottom x-axis, the left y-axis temperature in degrees and a right-hand y-axis showing percentage humidity. Am I asking too much?
Finally can I please request no Ajax, or other "stuff" other than php, html, JSON, and javascripts if possible?
Any help on formatting my question would be much appreciated :-)

If I echo the $json_data I get this type of result, but bear in mind it is dynamic data and changes every hour so it must be read from json_data every time the page is accessed:
[{"Timestamp":"10:04 02/01/21","temperature":"5","humidity":"66"},{"Timestamp":"10:19 02/01/21","temperature":"6","humidity":"65"},{"Timestamp":"10:35 02/01/21","temperature":"6","humidity":"64"},{"Timestamp":"10:50 02/01/21","temperature":"6","humidity":"64"},{"Timestamp":"11:06 02/01/21","temperature":"6","humidity":"64"},{"Timestamp":"11:21 02/01/21","temperature":"7","humidity":"63"},{"Timestamp":"11:34 02/01/21","temperature":"10","humidity":"66"},{"Timestamp":"04:21 02/01/21","temperature":"15","humidity":"64"},{"Timestamp":"04:36 02/01/21","temperature":"16","humidity":"61"},{"Timestamp":"04:51 02/01/21","temperature":"15","humidity":"59"},{"Timestamp":"05:07 02/01/21","temperature":"15","humidity":"60"},{"Timestamp":"05:22 02/01/21","temperature":"14","humidity":"61"}]
You need to format your data to the series structure required by Highcharts. The rest of the requirements are achievable by using chart options - please check xAxis and yAxis properties in API.
var data = <?= $json_data?>
var series = [{
name: "temperature",
data: []
},
{
name: "humidity",
data: [],
yAxis: 1
}
];
data.forEach(function(dataEl) {
series[0].data.push([
new Date(dataEl.Timestamp).getTime(),
Number(dataEl.temperature)
]);
series[1].data.push([
new Date(dataEl.Timestamp).getTime(),
Number(dataEl.humidity)
]);
});
Highcharts.chart('container', {
series: series,
yAxis: [{

you can achive with below code but when you choosing chart first know the purpose and create json data accroding to the series use apexcharts for free

I'm trying to display average grades for each individual assignment but I'm getting no luck displaying it within a Highchart Column. It displays just the legend and "where the graph should be".
I have my div <div id="container"></div> as well as the necessary SQL code:

Actual outcome
Actual problem is in php $json_data2;
Instead of
$json_data2=array();
$json_data2['name'] = 'Grade';
$row2->execute();
foreach($row2 as $rec2)
{
$json_data2['value'][]=$rec2['Grade'];
}
it should be
$json_data2=array();
$json_data2['name'] = 'Grade';
$row2->execute();
foreach($row2 as $rec2)
{
$json_data2['value'][]=intval($rec2['Grade']); /*intval()*/
}
This will result in correct JSON string with array of numbers instead of array of string
final output [{"name":"Assignments","value":["Find Hidden Data","Google Hacking","Caine Testing","Penetration Testing","FA 2"]},{"name":"Grade","value":[99,70,80,47.5,70,40]}]
In your current JSON string,
this is demonstration to show when array of string ["99", "70","80", "47.5", "70", "40"] is converted to array of numbers [99, 70,80, 47.5, 70, 40] then only chart works as desired
var data = [{

Hope this gives you enough explanation
I'm trying to use highcharts to draw data from php json.
the php works ok but i dont know how to make the json an input.
Speciffically 'm trying to put the data on single Gauge Chart like the one on the example, but i can't configure the script to read the json.
The URL si this: php/KPItonsStock.php
<?php
function getArraySQL(){
$startd = "29964";
$endd = "29968";
$dsn = "prueba";
$connect = odbc_connect( $dsn, '', '' );
$query = "
Select SUM(TON_DESCARGADO) AS data
from
(Select unit,[load],enum_LOAD.[name],SUM(dumptons) as TON_DESCARGADO
from hist_dumps inner join hist_loclist on hist_dumps.shiftindex = hist_loclist.shiftindex
and hist_dumps.loc = hist_loclist.locid
inner join enum_LOAD on hist_dumps.[load] = enum_LOAD.[num]
where hist_dumps.shiftindex between '$startd' and '$endd'
GROUP BY loc,UNIT,unit#,[load],enum_LOAD.[name])TEMP1
where unit = 'Stockpile'
GROUP BY unit
order BY UNIT";
if(!$rs = odbc_exec($connect, $query)) die();
$rawdata = array();
$i=0;
while($row = odbc_fetch_array($rs))
{
$rawdata[$i] = $row;
$i++;
}
odbc_close( $connect );
return $rawdata;
};
$data = getArraySQL();
echo json_encode(($data), JSON_NUMERIC_CHECK);
and the result is this:
[{"data":29655.88482666}]
so i need to put information from that URL to the gauge chart.
Im trying with getjson, but I'm missing something, because the chart loads but not the data.
This is the otriginal highchart example

I get the graphic but it doesnt load any data
Data needs to be an array. Make your backend return
[{
"data": [29655.88482666]
}]

session_start();
$username = $_SESSION['username'];
$quizes=null;
$score=array();
$i=0;
$result = mysql_query("SELECT * FROM `score` WHERE `username`='$username'") or die(mysql_error);
while($rows=mysql_fetch_array($result)) {
$quizes= $quizes. "'".$rows['quiz']."',";
$score[$i]=$rows['score'];

Here js will import data from mysql using data.php file and supply it to our chart
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";
}
data.php will simply print value on page that we will use for chart.
You can use this method with multiple charts on same page and no more files will required for more then single chart.
It will output like

I think your getting data in string format. convert data to integer like this way,
var mk1=<?php echo $score[1] ?>;
to integer: +mk1 // and check typeof +mk1
Here is the demo http://jsfiddle.net/XF293/
I advice to consider use json_encode() in php and return all values as single array. Then use $.getJSON() to avoid problems with printing values. As a result how your data looks like? I mean in javascript.
I am trying to get data from my mysql into Highcharts bar graph. I have the data from mysql that includes a port number and average bytes per port. Here is what I have for my php query and html page. The data (average bytes) shows up on the graph just fine. I can't get the categories (port) data to display.
<?php
$con = mysql_connect("localhost","root","kdkdkdk") or die(mysql_error());
mysql_select_db("silk", $con);
$result = mysql_query("SELECT dstPortNum,avgByte FROM statistic_avgbytesport ORDER BY avgByte DESC LIMIT 10;");
$rows = array();
while($r = mysql_fetch_array($result)) {
$row[0] = $r[0];
$row[1] = $r[1];
array_push($rows,$row);
}
print json_encode($rows, JSON_NUMERIC_CHECK);
#print json_encode($rows[0][0], JSON_NUMERIC_CHECK);
mysql_close($con);
?>
And my html page to display the graph.

You can use something like this:
$.getJSON("averageBytesPerPort.php", function(json) {
var options = {
chart: {
renderTo: 'avgbytes'
},
title: {
text: 'Average Bytes Per Port'
},
pane: {
size:'80%'
},
xAxis: {
title: {
text: 'PORTS'
},
categories: data.categories
},
yAxis: {
min: 0,
title: {
text: 'Bytes'
}
},
series: [{
type: 'bar',
name: 'Average Bytes',
data: data
}]
}
chart = new Highcharts.Chart(options);
});
how the hell on earth your data is shown , you have not put the $conn as the second parameter of the
mysql_query();
it should be
$result = mysql_query("SELECT dstPortNum,avgByte FROM statistic_avgbytesport ORDER BY avgByte DESC LIMIT 10;",$conn);
