Im stuck at trying to get updated values from the JSON array and plotting it on canvasJS.
Here is my JSON array for sensor 1:
[{
"Date": "2020-01-24 07:35:46",
"sensorValue": 213
}, {
"Date": "2020-01-24 07:35:46",
"sensorValue": 433
}, {
"Date": "2020-02-10 06:03:36",
"sensorValue": 321
}, {
"Date": "2020-02-10 06:03:36",
"sensorValue": 43
}, {
"Date": "2020-02-12 03:30:57",
"sensorValue": 4321
}]
Below is my index2.php file
the updateChart function doesn't seem to work. Im not sure if this is the right way to do it.
the rationale behind the code: I wish to update the graph every few seconds with updated values retrieved thru php. if there are no updated values, the array should not change. hence the reason behind the for-loop and the date comparison.
<?php

I can't comment, but I think the problem lies in the way you load the data (or the lack of it).
Basically you are loading the data on the PHP page render once, and that is all.
You need some ajax requests periodically to load the data instead of the PHP echo in the updateChart method. (In the initialization part it is fine)
$.ajax({
type: "GET",
url: 'getSensorData.php',
dataType: "text",
async: false,
success: function(data){
sensor1DataNew = data;
}
});
Something like this might work (with a little jquery)
I am writing a PHP script that uses Twitters API's to get a response of tweets in JSON. I am then using the id's in this JSON as parameters in Twitter's widgets.createTweet() function.
The official twitter documentation for this can be found here.
I believe the problem is at the point where I am trying to icnlude the Twitter widgets.js file within my PHP script.
Here is my entire PHP script with my keys and tokens redacted:
<?php
echo "<h2>Simple Twitter API Test</h2>";
require_once('TwitterAPIExchange.php');
$settings = array(
'oauth_access_token' => ""
'oauth_access_token_secret' => ""
'consumer_key' => ""
'consumer_secret' => ""
)
$url = "https://api.twitter.com/1.1/statuses/user_timeline.json";
$requestMethod = "GET";
if (isset($_GET['user'])) {$user = preg_replace("/[^A-Za-z0-9_]/", '', $_GET['user']);} else {$user = "iagdotme";}
$getfield = "?screen_name=$user&count=$count";
$twitter = new TwitterAPIExchange($settings);
$string = json_decode($twitter->setGetfield($getfield)
->buildOauth($url, $requestMethod)
->performRequest(),$assoc = TRUE);
if(array_key_exists("errors", $string)) {echo "<h3>Sorry, there was a problem.</h3><p>Twitter returned the following error message:</p><p><em>".$string[errors][0]["message"]."</em></p>";exit();}
$number_tweets = count($string['statuses']);
// THIS IS THE PROBLEM AREA ///////////
echo "<script sync src='https://platform.twitter.com/widgets.js'></script>"
echo "<div class='cols'>";
foreach ($tweet_array['statuses'] as $tweet ) {
$id = $tweet["id"];
echo "<div class='grid-item'><div id='container-$id'></div></div>";
$js_array[] = "twttr.widgets.createTweet('$id', document.getElementById('container-$id'));";
}
echo "</div>";
echo '<script>';
$t = 1;
foreach ($js_array as $js) {
echo $js;
$t++;
}
echo '</script>';
?>
I believe the problem is where I am trying to include the js file from https://platform.twitter.com/widgets.js
It seems to me like everything else here should work. This php file doesn't give me any errors when I try to open it in a browser. I am stuck.
What I'm tyring to do with this code:
make an API call to Twitter and retrieve a set of tweets
use the id's in those tweets to pass
How am I trying to do it:
Using php I have made a successful API call to Twitter with the assistance of an open sourced php library/api wrapper.
store the JSON response in an array, loop through that array getting the tweet id's (attributes for each tweet within the json)
use those id's as parameters for twitter's createTweet function
What my problem is:
I think the problem is, is that my code doesn't know what I mean when I use the twttr.widgets.createTweet() js function because htts://platform.twitter.com/widgets.js is not included properly.
To reiterate, this is where I am trying to include that file:
echo "<script sync src='https://platform.twitter.com/widgets.js'></script>"
Is that piece included properly? If so, are there other things that pop out as erroneous?
Here is a sample of the JSON response from the twitter API call.

If you want to know what syntax errors you have in runtime use phpstorm.
I fix errors and now code looks like this
and your script will connect in php file.

];
$url = "https://api.twitter.com/1.1/statuses/user_timeline.json";
$requestMethod = "GET";
if (isset($_GET['user'])) {
$user = preg_replace("/[^A-Za-z0-9_]/", '', $_GET['user']);
} else {
$user = "iagdotme";
}
$getfield = "?screen_name=$user&count=$count";
$twitter = new TwitterAPIExchange($settings);
$string = json_decode($twitter->setGetfield($getfield)
->buildOauth($url, $requestMethod)
->performRequest(),$assoc = TRUE);
if(array_key_exists("errors", $string)) {
echo "<h3>Sorry, there was a problem.</h3><p>Twitter returned the following error message:</p><p><em>".$string["errors"][0]["message"]."</em></p>";exit();
}
$number_tweets = count($string['statuses']);

You will get results on the fusioncharts website if you search up what I asked, but it is not exactly what I am looking for.
I am querying data from a MySQL database, and putting this data into a fusion chart to display on my webpage. I want there to be 2 graphs on the same page, and when you click on one of the datapoints on the parent graph, the child graph will display the "drilled down" graph. How can I do this? As of right now I can press on the parent graph and it will open the child graph on a new webpage. This is the code for the home page with the parent graph. The file is named "dept.php".

Back
<div id="chart-1"><!-- Fusion Charts will render here--></div>
</body>
</html>
n number of charts can be rendered in a single page using FusionCharts.
Store their chart references, e.g. in an associative array.
Use the dataplotClick event to capture the event being generated by clicking on a data.
Inside the callback, use the setJSONData to update the child chart, one wanna update.
A dummy code for this would be:
FusionCharts.ready(function () {
var chart1 = new FusionCharts({
type: 'msstackedcolumn2d',
renderAt: 'chart-container1',
width: '550',
height: '350',
dataFormat: 'json',
dataSource: {
// enter the json data here
},
"events": {
"dataplotClick": function(eventObj, dataObj) {
/* so every time a dataClickEvent is being triggered from the data plot,
a new json `json2` is fetched from a sql query and
chart2 is updated with it.*/
chart2.setJSONData(json2);
}
}
}
}).render();
});
Couple of days back I created this fiddle, hope this becomes useful here too. Instead of doing a SQL query, here we have a generalised data, every time a click is made, it internally makes a function call, and creates a data dynamically out of it. Lot of function calls for making it entirely dynamic might make the code look complex. But the basic philosophy I shared in the dummy code avobe is the same here.
The snippet version for the code for a quick reference.Better to run the result in full page to check whats exactly happening.

I want to render the data depending on account_id (in this case account_id = 1) to get the following JSON:
{
"data": [{
"date": "2006-01-03",
"dataSet01": "44.23",
"dataSet02": "62.75",
"dataSet03": "25.95"
}, {
"date": "2006-02-01",
"dataSet01": "45.85",
"dataSet02": "59.37",
"dataSet03": "27.59"
}, {
"date": "2006-03-01",
"dataSet01": "45.54",
"dataSet02": "60.86",
"dataSet03": "27.04"
}],
"events": [{
"dataSet01": [{
"date": "2006-01-03",
"title": "Analyst opinion change",
"text": "A",
"description": "Upgrade by Bank from Sell to Hold"
}, {
"date": "2006-02-01",
"title": "Dividend",
"text": "D",
"description": "Amount: 0.30"
}, {
"date": "2006-03-01",
"title": "Analyst opinion change",
"text": "A",
"description": "Upgrade by Bank from Sell to Hold"
}]
},{
"dataSet03": [{
"date": "2006-01-03",
"title": "Analyst opinion change",
"text": "A",
"description": "Upgrade by Bank from Sell to Hold"
}, {
"date": "2006-02-01",
"title": "Dividend",
"text": "D",
"description": "Amount: 0.30"
}, {
"date": "2006-03-01",
"title": "Analyst opinion change",
"text": "A",
"description": "Downgrade by Bank from Buy to Hold"
}]
}]
}
I'm struggling to build the json though. As of right now I'm rendering the data like this:
$query = "SELECT date, price
FROM datatable
WHERE account_id = 1
ORDER BY date ASC";
$result = mysql_query( $query );
$data = array();
while ( $row = mysql_fetch_assoc( $result ) ) {
$data[] = $row;
}
return json_encode( $data );
Obviously this returns the json with price as label for each record value (price). How should the query look like instead to render the above json example?
$query = "SELECT *
FROM datatable
WHERE account_id = 1
ORDER BY date ASC";
$result = mysql_query( $query );
// Define temporary arrays
$data = array();
$events = array();
while ( $row = mysql_fetch_assoc( $result ) ) {
// Assemble the data grouped by date and dataset
if ( !isset($data[$row['date']]) )
{
$data[$row['date']] = array(
'date' => $row['date'],
);
}
// Inject dataSet in $data grouped by date
if ( !isset($data[$row['date']][$row['dataSet']]) )
{
$data[$row['date']][$row['dataSet']] = $row['price'];
}
// Assemble events grouped by dataSet
if ( !isset($events[$row['dataSet']]) )
{
$events[$row['dataSet']] = array();
}
$events[$row['dataSet']][] = array(
'date' => $row['date'],
'title' => $row['title'],
'text' => $row['type'],
'description' => $row['description']
);
}
// Remove date keys
$data = array_values($data);
return json_encode(array(
'data' => $data,
'events' => $events
));
