i wannna make a line graph using highchart JS with data from my SQL, but unfortunately the graph just shown like this :
the graph just shown a Xline and Yline but not a data
and this is my sql code
$sqlX=mysql_query("SELECT DISTINCT DAY(tgl_daftar) as value FROM pasien WHERE MONTH(tgl_daftar) = '06' AND YEAR(tgl_daftar)='2016'")or die(mysql_error()) ;
and this my php and JS code :
<script src="js/jquery.min.js"></script>
<script src="js/highcharts.js"></script>
<script src="js/exporting.js"></script>
<script type="text/javascript">
var chart1 ;
$(document).ready(function() {

In $(document).ready(function(){}); I'm defining the properties how my chart is drawn, what comes to x-axis and y-axis and properties of it. But, now I want to build a function in which I pass argument whether I want to draw high chart or canvas and then that function draw chart. How to start this? Can anyone help?
<?php
//dummy data
$result['day'] = array('Sun', 'Man', 'Tue', 'Wed');
$result['amount'] = array(1, 32, 324, 3531, 15, 6);

//$result['chartType'] = 'normal'; //this one to draw normal chart

Note:
If you want to change the properties dynamically follow the same thing you did for x-axis values for example if you want to change the title then
title: {
text: '<?php echo $result["title"] ?>',
align: 'center'
},
Look at the official documentation. You have to call Highcharts.chart('div-chart', { ... your settings ... }. You can assign this to a variable, but not to your div like you did above. And what do you mean with draw canvas OR Highchart?
I think what Thamaraiselvam ment was:
$(document).ready(function() {
drawChart(chart_type, args...);
});
function drawChart(chart_type, args....){
if (type === 'highchart') {
drawHighChart(args);
} else if (type === 'canvas'){
drawCanvas(args);
}
}
function drawHighChart(args){
}
function drawCanvas(args){
}
Not directly related but still. I suggest you to look on the side of Jquery which gives the possibility to produce a lot of fancy graphic output with usually less effort than with javascript. see this documentation. Greetings andy
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;
}
?>

<?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.
Good day guys. So I've got some kind of problem of my highcharts pie, where I've got only two items/legends where 1995 and 1996. I've got a data in 1995 where there are 2 and 1996 is 0.
It displays the pie chart, but the problem is that it's wrong in percentage. As you can see in the image below it show both the 1995 and 1996.
The 1995 should be in 100% and not in 10% because i've got only two items, the 1996 is correct however because i've got no data.
Here is my php code
<?php
require '/db/database_configuration.php';
$_1995 = mysqli_query($conn, "SELECT COUNT(*) AS Total FROM `tblalumni` WHERE yeargrad LIKE '1995' and alum_status LIKE 2");
$_1996 = mysqli_query($conn, "SELECT COUNT(*) AS Total FROM `tblalumni` WHERE yeargrad LIKE '1996' and alum_status LIKE 2");
$_1995 = mysqli_fetch_array($_1995);
$_1996 = mysqli_fetch_array($_1996);
// displays zero if none
if (empty($_1995['Total'])) { $_1995 = '0'; } else { $_1995 = $_1995['Total'];}
if (empty($_1996['Total'])) { $_1996 = '0'; } else { $_1996 = $_1996['Total'];}
$ans_1995 = '1995';
$ans_1996 = '1996';
$Data95 = $_1995;
$Data96 = $_1996;
?>
Here is my javascript
<script type="text/javascript">
$(function () {
