I am trying to pull data from mysql and display on highchart bar graph, but I am not sure where my code is incorrect. The result is a blank page.
The code could not be wrong as I have taken it from the index.html file that highchart provides, but it doesn't work for some reason. Could anyone check and let me knpw where I am making any error?

I am using HighCharts and im showing temperature on the graph. I was thinking that is it possible to show data for a single day only or 1 week or over a month using highchart graph. Right now I get all the data which is from the 1st record to the latest one from MySQL DB . Here is the code .
this is data.php -
<?php
$con = mysql_connect("192.168.100.107:3306","root","hannan786");
if (!$con) {
die('Could not connect: ' . mysql_error());
}
mysql_select_db("pi", $con);
$sth = mysql_query("SELECT * FROM temperature ");
$rows = array();
$rows['Temperature'] = 'temperature';
while($r = mysql_fetch_array($sth)) {
$rows['data'][] = $r['temperature'];
}
$result = array();
array_push($result,$rows);
print json_encode($result, JSON_NUMERIC_CHECK);
mysql_close($con);
?>
And this is the code for the main Page where the graph data is displayed -
<!DOCTYPE HTML>

Right Now I get this as output -
You can use the method setExtremes() of the Highcharts Api. You only have to provide min and max value, that in your case consists of the same Date Object, I think.
This is a fiddle as an example on how to use it.
chart.xAxis[0].setExtremes(
Date.UTC(2007, 0, 1),
Date.UTC(2007, 11, 31)
);
Docs are here: http://api.highcharts.com/highstock#Axis.setExtremes
I am trying to fetch data between two dates using Ajax and displaying the graph using HighCharts.

I'm not sure why you want change event on div, try change into this :
<div id="dynamic_data">
<input type="date" id="startdate">
<input type="date" id="enddate">
// add button
<input type="button" id="myBtn">
</div>
JS
// this function called after button was clicked
$('#myBtn').click(function(){
var startdate = $('#startdate').val(),
enddate = $('#enddate').val();
getAjaxData(startdate, enddate);
});
// i'm assume the queries from database already worked out
// simply use this below code to send parameter during request
function getAjaxData(startdate, enddate) {
$.getJSON( "data/data-basic-colm-ajax.php", { startdate: startdate, enddate: enddate }, function(json) {
options.xAxis.categories = json[0]['data']; //xAxis: {categories: []}
options.series[0] = json[1];
chart = new Highcharts.Chart(options);
});
}
If you wanna display the chart at first load page, then call getAjaxData(startdate, enddate) with default value for date.
I am having difficulties to get the data received from PHP script and set it into the Gauge graph.
I am getting the json result correctly, just do not know how to set it to the right Highchart gauge variables (gaugeOptions).
I'd like to put in #container-C_2 the returned values from PHP, so configure the min, max and set the value on the gauge graph.
strong text
I think In the $.getJSON() body I need to call
$('#container-C_2').highcharts( with some arguments, but don't know how..
Can someone help me here?
Many thanks.
PHP
$result = array();
$result['name'][0] = 'A';
//--some values
$result['min'][] = 10;
$result['max'][] = 50;
$result['val'][] = 20;
$json = array();
array_push($json,$result);
print json_encode($json);

I've created a column chart from data I've retrieved from mysql.
The data are two series of data.
Chart is working.
However in the resulting graph I would like to give the series a different pointWidth.
PHP script for retrieving the Mysql data:
<?php
$con = mysql_connect("localhost","xxxx","xxxx");
if (!$con) {
die('Could not connect: ' . mysql_error());
}
mysql_select_db("pvdag", $con);
$query = mysql_query("SELECT maand, OpbrengstPV, OpbrengstTheor FROM maandgegevens where YEAR(periode) = 2013");
$category = array();
$category['name'] = 'maand';
$series1 = array();
$series1['name'] = 'OpbrengstPV';
$series2 = array();
$series2['name'] = 'OpbrengstTheor';
while($r = mysql_fetch_array($query)) {
$category['data'][] = $r['maand'];
$series1['data'][] = $r['OpbrengstPV'];
$series2['data'][] = $r['OpbrengstTheor'];
}
$result = array();
array_push($result,$category);
array_push($result,$series1);
array_push($result,$series2);

You can set pointWidth on particular serie, not in plotOptions, like in the example:
series: [{
data: [49.9, 71.5, 106.4, 129.2, 144.0, 176.0, 135.6, 148.5, 216.4, 194.1, 95.6, 54.4]
}, {
pointWidth: 50,
data: [83.6, 78.8, 98.5, 93.4, 106.0, 84.5, 105.0, 104.3, 91.2, 83.5, 106.6, 92.3]
}]

In your php...where you make the query to the database....in the while loop, you need to construct and string and in the end of the loop the string should looks like:
$my_data = "['ABC', 6597],
['XYZ', 4479],
['PQR', 2075],
['qqq', 1706],
['ttt', 1030],
['Others', 450] ";
Then in your javascript file, you should have a line like this
series: [{
type: 'pie',
name: 'Pie Data',
data: [
<?php echo $my_data; ?>
]
}]
It's very simple.
Saludos.
