Sir good evening. i have a highchart graph which display all the month in the present year. All i want is to add a drop down list months which if i choose a month the graph will change data also specifically in the month chosen in the drop down. Pls help me
heres my data.php code. This code will just get the data without the specific month and year. Now i want is to put a dropdown list of month e.g january->december with the present year and if i choose a month from the drop down the graph will also change data.
<?php
$con = mysql_connect("localhost","root");
if (!$con) {
die('Could not connect: ' . mysql_error());
}
mysql_select_db("bfp", $con);
$query = mysql_query("select city, sum(Miscellaneous) as Miscellaneous,
sum(Residential) as Residential, sum(Assembly) as Assembly, sum(Educational) as `Educational, sum(Institutional) as Institutional, sum(Mercantile) as Mercantile, sum(Business) as Business, sum(Industrial) as Industrial, sum(Storage) as Storage, sum(Mixed) as Mixed, sum(total) as total from report_structure group by city ");`
$category = array();
$category['name'] = 'City';
$series1 = array();
$series1['name'] = 'Business';
$series2 = array();
$series2['name'] = 'Storage';
$series3 = array();

you can do it in 2 different ways.
maintain the entire data month-wise as separate data sets. append them to make an entire year data. when user selects any month in the dropdown then update the series data or re-render the chart
you can use setExtremes() method for xAxis depending on the month selected in the drop down.
if user selects june set xAxis extremes from 1st Jun to 30th Jun.
Hope this will help you

I have a page that dynamically updates a HighCharts graph from a multiselect dropdown.

</html>
Now, my analysisajax.php file looks like this:
<?php
header("Content-type: text/json");
// Initialize the session
session_start();
// Include config file
require_once "config.php";
$jsonObject = array();
$yaxis = 0;
foreach($_POST["f"] as $v) {

$sql = "SELECT $v FROM log WHERE id_user = " . $_SESSION["id_user"];
$result = $link->query($sql);
while($row = $result->fetch_row()) {
$data[] = $row[0];
}
$jsonObject[] = array(
"name" => $v,
"data" => $data,
"yAxis"=>$yaxis
);
$yaxis++;
}
$myJSON = json_encode($jsonObject, JSON_NUMERIC_CHECK);
echo $myJSON;
// Close connection
mysqli_close($link);
?>
When I'm selecting 1 value from the form, the graph loads without problem, but as soon as more than 1 value is selected from the dropdown, the graph fails with the following trace:
highcharts.src.js:498 Uncaught Error: Highcharts error #18: www.highcharts.com/errors/18

I feel that the issue is coming from my dynamic construction of yAxis but can't find a way to make it work. Any idea? Thanks a lot.
I eventually made it work with the following solution:
In the analysisajax.php script, I no longer generate the yaxis. I only send name and data.
The code to generate the graph now looks like this:
var updateChart = function(json) {
//console.log(json)
var options = {
chart: {
renderTo: 'graph',
type: 'line',
zoomType: 'x'
},
title: { text: null },
yAxis:[],
legend: {
layout: 'vertical',
align: 'right',
verticalAlign: 'bottom'
},
plotOptions: {
series: {
label: {
connectorAllowed: false
},
pointStart: 0
}
},
series: [],
tooltip: { shared: true }
}
var chart = new Highcharts.Chart(options);
// update axis and series
for (i=0; i<json.length; i++) {
// add axis
chart.addAxis({ title: { text: json[i].name } });
// add serie
var a = chart.series.length;
var seriesOptions = {
name: json[i].name,
data: json[i].data,
yAxis: a
}
chart.addSeries(seriesOptions,true);
chart.options.series.push(seriesOptions);
}
}
$(document).ready(function() {
$('#f').change(function() {
var requestParams = { f: $('#f').val() };
$.post('analysisajax.php', requestParams, updateChart);
//return false;
});
});
I'm working with Highcharts and Highstock from a few weeks ago. Step by step, following the documentation and help online, I have builded some charts with interesting options. But now I have a question, and my skills with mysql and php are limited.
I get temperature values from a data base, every minute. I use a php file to connect to database, and then I build the chart. Now, I want to update the chart like in this example. But I can't find a right way. I was reading in Highcharts documentation, and Stackoverflow some answers, but I can't implement into my code.
I was working in 2 ways to implement the dynamic updates. The first one is:
<?php
function conectarBD(){
$server = "localhost";
$usuario = "user";
$pass = "password";
$BD = "databasename";
$conexion = mysqli_connect($server, $usuario, $pass, $BD);
if(!$conexion){
echo 'Ha sucedido un error inexperado en la conexion de la base de datos<br>';
}
return $conexion;
}
function desconectarBD($conexion){
$close = mysqli_close($conexion);
if(!$close){
echo 'Ha sucedido un error inexperado en la desconexion de la base de datos<br>';
}
return $close;
}
function getArraySQL($sql){
$conexion = conectarBD();
if(!$result = mysqli_query($conexion, $sql)) die();
$rawdata = array();
$i=0;
while($row = mysqli_fetch_array($result))
{
$rawdata[$i] = $row;
$i++;
}
desconectarBD($conexion);
return $rawdata;
}
$sql = "SELECT Probe1,Time from table2;";
$rawdata = getArraySQL($sql);
for($i=0;$i<count($rawdata);$i++){
$time = $rawdata[$i]["Time"];
$date = new DateTime($time);
$rawdata[$i]["Time"]=$date->getTimestamp()*1000;
}
?>
<HTML>
<BODY>
<meta charset="utf-8">

<div id="container">

<script type='text/javascript'>
$(function () {
$(document).ready(function() {
Highcharts.setOptions({

}
});
var chart;
$('#container').highcharts({
chart: {
type: 'spline',
animation: Highcharts.svg, // don't animate in old IE
marginRight: 10,
events: {
load: function () {
var series = this.series[0];
setInterval(function () {
<?php
for($i = 0 ;$i<count($rawdata);$i++){
?>
series.addPoint([<?php echo $rawdata[$i]["Time"];?>,<?php echo $rawdata[$i]["Probe1"];?>], true, true);
<?php } ?>
}, 90000);
}
}
},
title: {
text: 'Tunnel temperature'
},
xAxis: {
type: 'datetime',
tickPixelInterval: 150
},
yAxis: {
title: {
text: 'ºC'
},
plotLines: [{

}]
},
tooltip: {
formatter: function() {
return '<b>'+ this.series.name +'</b><br/>'+

'<b>'+ Highcharts.numberFormat(this.y, 1) +'</b>';
}
},
legend: {
enabled: true
},
exporting: {
enabled: true
},
series: [{
name: 'Probe-1',
data: (function() {
var data = [];
<?php
for($i = 0 ;$i<count($rawdata);$i++){
?>
data.push([<?php echo $rawdata[$i]["Time"];?>,<?php echo $rawdata[$i]["Probe1"];?>]);
<?php } ?>
return data;
})()
}]
});
});
});
</script>
</html>
And this other way:
Connection to datatest2.php:
<?php
//convert the date values to Unix Timestamp
//Convert from 2017-02-28 19:30:01 to Tuesday, February 28 2017 19:30:01
$con = mysql_connect("localhost","username","password");
if (!$con) { die('Could not connect: ' . mysql_error()); } mysql_select_db("databasename", $con);
$result = mysql_query("SELECT * FROM table2");
while ($row = mysql_fetch_array($result)) {
$uts=strtotime($row['Time']); //convertir a Unix Timestamp
$date=date("l, F j Y H:i:s",$uts);
//echo $valor3 . “\t” . $row[$valor2]. “\n”;
echo $date . "\t" . $row['Probe1'] . "\n";
}
mysql_close($con); ?>
And the php file for the chart:

Can you help me to find and fix the mistake?
Thanks!
Alex.
Using a combination of your first example and the JSFiddle that you posted, I would try something like this:
chart: {
events: {
load: function () {
var series = this.series[0];
setInterval(function () {
<?php
for($i = 0 ;$i<count($rawdata);$i++){
?>
series.addPoint([<?php echo $rawdata[$i]["Time"];?>,<?php echo $rawdata[$i]["Probe1"];?>], true, true);
<?php } ?>
}, 1000);
}
}
}
Note that I have no idea whether your PHP code there is actually retrieving the data that you wanted, I have simply copied it from your example and made the assumption that that part of the code was ok.
The key here is the chart.events.load property, this takes a function that fires once the chart has finished loading. By calling setInterval here, your function will fire continuously after the chart finishes loading the first time.
By calling series.addPoint, your chart will redraw every time a new point is added, which I believe is what you want.
More information is available here about the load property.
Relatively new to HighCharts, PHP and JS but continuing to learn. I have searched extensively on the web but have not found anything that works so far.
I have a listing website that displays information on a variety of hospitals. As part of this offering, I am looking to show salary information unique to each hospital (~4,800) in HighCharts, using the WP post ID as the identifier.
I have a static chart showing across all hospitals as a placeholder right now but would like make this dynamic based on the individual hospital in question. I tried to use an Ajax POST command to push the right data without any luck thus far.
Any help or guidance would be greatly appreciated!

Here I am using highchart with codeigniter. I got highchart record with graph but I want record comes from mysql database field of "zreadactivity" in tooltip. I could not get proper name in tooltip for "zreadactivity" as it contains record. So, I just want to know that where I am stuck?
Here is my code:
Controller:
public function branchwiseactivityavg()
{
$data = $this->Data->branch_wise_activities();
$category = array();
$category['name'] = 'EndDate';
$series1 = array();
$series1['name'] = 'TotalValue';
$series2 = array();
$series2['name'] = 'zreadactivity';
foreach ($data as $row)
{
$category['data'][] = $row->EndDate;
$series1['data'][] = $row->TotalValue;
$series2['data'][] = $row->zreadactivity;
}
$result = array();
array_push($result,$category);
array_push($result,$series1);
array_push($result,$series2);
print json_encode($result, JSON_NUMERIC_CHECK);
}
Javascript:
<script type="text/javascript">
$(document).ready(function() {
var options = {
chart: {
renderTo: 'container5',
type: 'column',
marginRight: 130,
marginBottom: 25,

},

},
yAxis: {
title: {
text: 'TotalValue'
},
plotLines: [{

width: 1,
color: '#808080'
}]
},
tooltip:
{
formatter: function() { return ' ' +
'EndDate: ' + this.x + '<br />' +
'TotalValue: ' + this.y + '<br />' +
'zreadactivity: ' + this.series.name;
}
},

options.series[0] = json[1];
chart = new Highcharts.Chart(options);
});
});
</script>
zreadactivity table:
zreadacivity
---------------
Refund
Exchange
Voids
Cancel
Discount
Price Overwrite
One way is to create JSON where for series' data each point is defined as an array like:
[value_from_TotalValue, value_from_zreadactivity]
and set keys for series like:
series: [{keys: ['y','zreadactivity']}]
and in tooltip's formatter use this.point.zreadactivity to access zreadactivity.
Other option is to build this structure for series in JavaScript after getting JSON data.

Example without keys: http://jsfiddle.net/yhx2dp2g/1/

Here is data.php. I think there is nothing wrong about this php.
<?php
$con = mysql_connect("localhost","*****","*******");
if (!$con) {
die('Could not connect: ' . mysql_error());
}
mysql_select_db("test_youtube", $con);
$query = mysql_query("SELECT month, wordpress, codeigniter, highcharts FROM project_requests");
$category = array();
$category['name'] = 'Month';
$series1 = array();
$series1['name'] = 'Wordpress';
$series2 = array();
$series2['name'] = 'CodeIgniter';
$series3 = array();
$series3['name'] = 'Highcharts';
while($r = mysql_fetch_array($query)) {
$category['data'][] = $r['month'];
$series1['data'][] = $r['wordpress'];
$series2['data'][] = $r['codeigniter'];
$series3['data'][] = $r['highcharts'];
}
$result = array();
array_push($result,$category);
array_push($result,$series1);
array_push($result,$series2);
array_push($result,$series3);
print json_encode($result, JSON_NUMERIC_CHECK);
mysql_close($con);
