Reading MySQL data into highstocks

So this is the first time i have really worked with high charts i have some data reading into high charts from my MySQL database, but the next step is to try and set up a high stocks chart. Whenever i try and use the same method as i did with high charts the chart doesn't work? This is what i want to aim for - StockChartDemo
PHP Code:
$conn = new mysqli($servername, $username, $password, $dbName);
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
$sql = "(SELECT date AS time ,IFNULL(RH,'null')AS humidity
FROM test ORDER BY date DESC LIMIT 20) ORDER BY time ASC";
$result = $conn->query($sql);
if ($result->num_rows>0){
$count =0;
echo '[';
while($row=$result->fetch_assoc()){
echo '['.$row["time"].',' .$row["humidity"].']';
$count++;
if ($count<"20"){
echo ',';
}
}
echo ']';
}else{
echo "[[],[]]";
}
$conn->close();
?>
html & jQuery:
<script src="https://code.jquery.com/jquery-3.1.1.min.js"></script>

Presuming your query is returning the correct data you want. (I'm not up for mocking it out to test your query)
You should switch out the following code, and all that in-between.
if ($result->num_rows>0){
//snip
}
To use json_encode() instead.
$series = [];
if ($result->num_rows > 0) {
while ($row = $result->fetch_assoc()) {
$series[] = [
$row["time"],
$row["humidity"]
];
}
}
header('Content-Type: application/json');
exit(json_encode($series));

How to display the sum in this graph. I have the same year in my database (2012) How can i add those 2 data? And display automatically in graph?

How to display the sum in this graph. I have the same year in my database (2012) How can i add those 2 data? And display automatically in graph? This is the codes of my sample:
<?php
$connect = mysqli_connect("localhost", "root", "", "testing");
$query = "SELECT * FROM account";
$result = mysqli_query($connect, $query);
$chart_data = '';
while($row = mysqli_fetch_array($result)) {
$chart_data .= "{ year:'".$row["year"]."', profit:".$row["profit"].",
purchase:".$row["purchase"].", sale:".$row["sale"]."}, ";
}
$chart_data = substr($chart_data, 0, -2);
?>
<script type="text/javascript">
config = {
data: [<?php echo $chart_data; ?>],
xkey: 'year',
ykeys: ['profit', 'purchase', 'sale'],

Passing Decimal string from php to jquery

I am trying to pass some formatted String from PHP to jQuery. But i am getting an error as
VM2203:3 Uncaught SyntaxError: Unexpected number in the browser.
Here is my code
<?php
$OSlist = [];
$category = "";
$pieData = "";
$curl = curl_init();
curl_setopt_array($curl, array(
CURLOPT_PORT => "8081",
CURLOPT_URL => "http://localhost:8081/api/devices/hoursBy/OSVersion",
CURLOPT_RETURNTRANSFER => true,
CURLOPT_ENCODING => "",
CURLOPT_MAXREDIRS => 10,
CURLOPT_TIMEOUT => 30,
CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
CURLOPT_CUSTOMREQUEST => "GET",
CURLOPT_HTTPHEADER => array(
"cache-control: no-cache",
),
));
$response = curl_exec($curl);
$err = curl_error($curl);
curl_close($curl);
if ($err) {
echo "cURL Error #:" . $err;
} else {
$decodeStr = json_decode($response, true);
foreach ($decodeStr as $item) {
$os = $item['_id']['os'];
if ($os == $selectedOS) {
if ($item['total_hours'] != 0) {
$OSlist[$item['_id']['version']] = $item['total_hours'];
// echo 'iOS'.$item['_id']['version'] . ' : ' . $item['total_hours'] ,"<br>";
}
}
}
ksort($OSlist);
foreach ($OSlist as $key => $val) {
// echo "$key = $val" . "<br>";
$category = $category . $key . ",";
$pieData = $pieData . "[" . $key . "," . $val . "],";
}
$pieData="[".$pieData."]";
echo $pieData;
// print_r($OSlist);
} ?>
<script >
$('document').ready(function () {
var jsArray = <?php echo $pieData; ?>;
alert(jsArray);
});
</script>
The Piedata output is
[[2.3.4,97.9],[4.0.3,11.6],[4.0.4,2.4],[4.1.1,15.1],[4.1.2,398.4],[4.2.1,45.8],[4.2.2,27.3],[4.3,321],[4.4.2,694.9],[4.4.4,478.7],[5,646.3],[5.0.1,177.5],[5.0.2,1210.5],[5.1,126.2],[5.1.1,524.4],[6,201.5],]
i actually need to pass this data to highchart pie graph to the data value.The following graph is for mobile version vs its utilization hours.
function loadPieGraph() {
// Radialize the colors
var android = <?php echo $androidhrs ?>;
var ios = <?php echo $ioshrs ?>;
var obj = [{
type: 'pie',
name: 'Browser share',
data: [
['4.1', '23.0'],
{
name: '5.0',
y: '40.2',
sliced: true,
selected: true
},
]
}];
Highcharts.getOptions().colors = Highcharts.map(Highcharts.getOptions().colors, function (color) {
return {
radialGradient: {
cx: 0.5,
cy: 0.3,
r: 0.7
},
stops: [
[0, color],
[1, Highcharts.Color(color).brighten(-0.3).get('rgb')] // darken
]
};
});
// Build the chart
$('#container').highcharts({
chart: {
plotBackgroundColor: null,
plotBorderWidth: null,
plotShadow: false,
type: 'pie'
},
title: {
text: 'Browser market shares. January, 2015 to May, 2015'
},
tooltip: {
pointFormat: '{series.name}: <b>{point.percentage:.1f}%</b>'
},
plotOptions: {
pie: {
allowPointSelect: true,
cursor: 'pointer',
dataLabels: {
enabled: true,
format: '<b>{point.name}</b>: {point.percentage:.1f} %',
style: {
color: (Highcharts.theme && Highcharts.theme.contrastTextColor) || 'black'
},
connectorColor: 'silver'
}
}
},
series: obj
});
}

This whole part:
foreach ($OSlist as $key => $val) {
// echo "$key = $val" . "<br>";
$category = $category . $key . ",";
$pieData = $pieData . "[" . $key . "," . $val . "],";
}
$pieData="[".$pieData."]";
echo $pieData;
// print_r($OSlist);
} ?>
<script >
$('document').ready(function () {
var jsArray = <?php echo $pieData; ?>;
alert(jsArray);
});
</script>
looks really faulty in nature.
You should rather:
$pieData = json_encode($OSlist);
and in the script tag you can simply do this:
jsArray = JSON.parse("<?php echo $pieData; ?>");
And then do the HighChart's relevant array formatting in the JS.
Or you can directly do the formatting first in PHP and do json encode the final form and directly pass it to js where again you will need to JSON.parse them again.
Always do data transactions in form of JSON in these types of cases.
Hope it helps.
Hope it helps.

Please help me anybody. I am new in jQuery and JavaScript.

if ($result->num_rows > 0) {
// output data of each row
while($row = $result->fetch_assoc()) {
echo "country: " . $row["country"];
}
}
You are still returning the country.
try
if ($result->num_rows > 0) {
// output data of each row
while($row = $result->fetch_assoc()) {
echo "category: " . $row["category"];
}
}

You can customise tooltip using onRegionTipShow method. Just take a look at example available here.
