I wrote a php script with target to use $.getJSON() function.#
The live-temp-data.php create an json file with data like this:Data
This is the result : linechart
what am I doing wrong ? Code below.

1) Open the web console, and you will see the following message :
https://www.highcharts.com/errors/25/
If you browse this page, you will have the error message :
Can't find Moment.js library
Using the global.timezone option requires the Moment.js library to be
loaded.
So import that library, or remove this option, and that problem should be solved.
2) your HTML document is invalid, everything is in the head section, you should have a body section that contains your graph container.
3) your JSON is not valid : ["[1584713222000, 6.5]","[1584713572000, 6.6]","[1584713989000, 6.7]", ...
You should not have quotes around the data items.

I'm trying to create column chart using data imported from csv file. I have tried every possible solution on the Internet but couldn't figure out the solution to my problem. I'm trying to show Shop Name on x-axis and Sales on y-axis.
Here is my code:
<!DOCTYPE html>

This is just to give you an example of how you can plot chart with Highchart while parsing .csv data. Code is simple and self explanatory.

74.4559979,31.5931715,Baghbanpura 239 - G T Road,Baghbanpura,49901
Points to be noted
Note that in .csv there are no space after comma, so .csv must follow that or you have to edit the logic to form shopNameData and salesData
Host both .html and .csv at one place in some server. Otherwise, in Google Chrome, you will get CrossOrigin error.
Here is the snapshot of Chart if you will copy the html and name the .csv as stores.csv in same directory of html and host in some server.
I am new to programming language so please consider my poor knowledge. Basically i am trying to use Highcharts for my project which takes data from a csv data source.
please take a look at:
flood forcast data
The chart shows 10 days flood forcast for a particular place. I want to have the ability to disable a data series by default, so that when you click on its legend item it shows, instead of hides. This will give me the ability to put many series on one graph, only show the Important ones, while allowing users to show additional series if they need. as an example: on load it will have day1, day3 and day5 "visible: true" and rest "visible: false." hope i made it clear
here goes my code:

Thanks in advance.
You can do this with the visible property, just add to your options:
series: [{
visible: false
}, {
visible: true
}]
series represents your array of series, in this example has two series, the first hidden and the second visible. You can check this fiddle that uses data csv too:

Hope it helps!
I am working on a project that will display a bar chart. The bar chart is working perfectly but when I try to pass an integer php variable to javascript variable and add the variable as an element of a list isn't working. below is my code. I don't know what is wrong with my source code. I spend several hours finding for solution online but I don't get any.
Looking forward to see your response.

For what it's worth, you should avoid interacting with javascript in this way. PHP works better when you're interacting with HTML, and let javascript be separate (this goes halfway towards using a true templating system, which you should do):
<?php
// page setup goes up here:
$ab = 6; // name your variables at little more descriptively, I don't know what this does
?>
<head>
<title></title>
<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.8.2/jquery.min.js"></script>

#container { height: 400px; min-width: 310px; max-width: 800px; margin: 0 auto; }
</style>
<script type="text/javascript">
$(function () {
console.log($('#ab-variable').val());
$('#container').highcharts({
chart: {
type: 'column',
options3d: {
enabled: true,
alpha: 10,
beta: 25,
depth: 70
}

series: [{
name: 'Sales',
// We're referencing our hidden field in the HTML

}]

<!-- we're including our variable here, in HTML, rather than in the javascript -->
<input type="hidden" id="ab-variable" value="<?= $ab; ?>">
<div id="container" style="height: 400px"></div>
</body>
... you can then look int the HTML and see that your hidden field has the correct value. If it's still not working, then you've got a problem with your javascript setup using highcharts.
If you write your code this way, you get the added benefit of being able to create a separate javascript file that will be cached at the client and they won't have to download it every time.
As is, it doesn't look like there's any inherent problem with your code, but re-factoring (when it's warranted) can sometimes suss out little bugs. To confirm that this code should work the way you want, I've added a console.log() call to ensure that your javascript can see your variable. To see anything more than that you'll have to provide a link to your page so we can see any errors that might be popping up.
I have a .json file (abc.json) and I want to plot graph using jqplot from two columns of this data. My approach is:
Converting json file data into array using jquery
Plotting graph from that array using jqplot
Then showing that graph on browser using html
However I am not able to do so as I am not very proficient in javascript.
My JSON data looks like follows:
[
{
"id":1,
"essid":"\"WiredSSID\"",
"mac":"08:00:27:b1:3e:4d",
"ip":"10.0.3.15",
"ss":-55,
"lon":-18.5333,
"lat":65.9667,
"alt":15.044444,
"acc":1,
"res":18058,
"pub_date":"2015-12-01 22:39:07.700953"
},
{
"id":2,
"essid":"\"WiredSSID\"",
"mac":"08:00:27:b1:3e:4d",
"ip":"10.0.3.15",
"ss":-55,
"lon":-18.5333,
"lat":65.9667,
"alt":15.044444,
"acc":1,
"res":16337,
"pub_date":"2015-12-01 23:13:52.639206"
},
However I want my javascript to read the data directly from JSON file and plot the graph for id vs res.
Below is a an incomplete code which I have written for this purpose which is missing some major process.
Can anyone please help me completing this code so that I can complete this academic project of mine. this would be really helpful.

Here is a working example. https://jsfiddle.net/9jk0jyvt/1/
I commented out the ajax request and replaced it with the json response you have provided above.
One thing to note is that you had the incorrect key for date. I switched it to pub_date.
I also swapped your axis labels to be correct.
$(document).ready(function() {
// The url for our json data
var url = 'mc_measurementne_new1.json';
data = [{
"id": 1,
"essid": "\"WiredSSID\"",
"mac": "08:00:27:b1:3e:4d",
"ip": "10.0.3.15",
"ss": -55,
"lon": -18.5333,
"lat": 65.9667,
"alt": 15.044444,
"acc": 1,
"res": 18058,
"pub_date": "2015-12-01 22:39:07.700953"
}, {
"id": 2,
"essid": "\"WiredSSID\"",

"pub_date": "2015-12-01 23:13:52.639206"
}];
populateGraph(data);
/*
$.ajax({
url: url,
dataType: "json",
success: function (data) {
populateGraph(data);
}
});
*/
function populateGraph(ret) {
var ID = [];
var Delay = [];
for (i = 0; i < ret.length; i++) {
// Save the data to the relevant array. Note how date at the zeroth position (i.e. x-axis) is common for both demand and supply arrays.
ID.push([ret[i].pub_date, ret[i].id]);
Delay.push([ret[i].pub_date, ret[i].res]);
}
var plot1 = $.jqplot('chart1', [ID, Delay], {

I've tried similar examples through stackoverflow as well as Highcharts Support, however still cannot get a graph to display properly. Trying to display a spline graph with data from a csv file with format hour,temperature as shown below in an example:
22,84
23,83
00,82
01,81
02,79
03,77
04,75

Thanks..
You need to add a two dimensional array as data. You can declare a global variable and add the data to that varible.
var chartData=[]
var dataTemp = new Array(parseInt(items[0]), parseInt(items[1]));
chartData.push(dataTemp);
and
series: [{
data: chartData
}]
