I am doing the temperature project needed to use flot to display the data. And I found guy doing almost same project as I did. Here is the link: temperature jquery flot
In the flot code, I replaced some code with data I wanted to put into .(only two place I replace, without getting php value to make it easy) like
var dat = [ [123456789, 20.9],[1234654321, 22.1] ];
yaxis: { min: 20, max: 20>, tickFormatter: function (v, axis) { return v.toFixed(axis.tickDecimals) +"°C " }},
Here is the code: Nothing happen when I display the html page. Please help !!

I formulate my answer here based on the comments.
First of all fix the "20>" value in the yaxis definition, then be sure that all the javascript files are in the same directory as the projectFlot.html file, and then that all the names correspond.
Another thing is that you are importing jquery.flot.js and jquery.js TWICE!
so remove the last line <script type="text/javascript" src="jquery.js"></script> and even the second <script type="text/javascript" src="jquery.flot.js"></script>.

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

Since i am new to Ajax so any help will be appreciated.
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);

In your integrated page, you load all javascript files once at the beginning of the integrated page and once again at the beginning of maindashoverall1.php. Remove the block in the maindashoverall1.php file.
You also have two lines (per block) where you load jquery.flot.axislabels.js. Remove one of those too.
im trying to style my flot charts similar to this:
this is my current chart:
here is my chart code,
<?php
include('Includes/connect.php');
?>

<?php

$result = mysql_query($sql) or die ("no query");

?>
<div id="chart1" style="width:700px;height:300px;"></div>
<script type="text/javascript">
//Chart1
var chart1Options = {
xaxis: {mode: "time", timeformat: "%Y-%m-%d"},

};
var dataset1 = { data: <?php echo json_encode($dataset1); ?>,};
$.plot($("#chart1"), [ dataset1 ], chart1Options);
</script>
</body>
</html>
can anyone help me out please? similar colours and also i cant seem to get hover data showing up either
thanks.
This should get you close to the appearance you want.
HTML:
<div id="placeholder" style="width:400px;height:300px;background-color: #6EB5F0"></div>
JS:
$(function () {
var plot = $.plot($("#placeholder"),[
{ data: [[0,0],[1,1],[2,4],[3,3],[4,5],[5,7],[6,9],[7,10],[8,8],[9,12]], color: 'white'}
], {
series: {
lines: { show: true, fill: true, fillColor: 'rgba(143, 198, 242, 0.7)' },
points: { show: true}
},
grid: { color: 'transparent' },
xaxis: {
color: 'white',
font: { color: 'white', family: 'sans-serif', size: 11}
},
yaxis: {
color: 'white',
font: { color: 'white', family: 'sans-serif', size: 11}
}
});
});
Result:
Fiddle here.
As far as your hover tooltips not working, there's a great example here. Follow that and if you still can't get it working, update your question with specifics and a minimal code sample that demonstrates the problem.
