PHP array data convert to JS ( Canvas JS )

Question

I am trying to make a graph of my own data (JS)which I have stored in a php array

Now I have to make some kind of loop to make(Javascript)

  dataPoints: [

              { x: 10, y: 10 },
              { x: 20, y: 15 },
              { x: 30, y: 25 },
              { x: 40, y: 30 },
              { x: 50, y: 28 }
              ]

Needs to be something like

 {x: $arraytime[0], y:arraycloud[0]) , 
 {x: $arraytime[1], y:arraycloud[1]) , 
 {x: $arraytime[2], y:arraycloud[2]) ,

etcetera.

I have no clue how to do this

You can use a json_encode for this, if you prepare the array in php, like this:

$arr = array();
for ($i = 0; $i < count($arraytime); $i++) {
    $arr[] = array('x' => $arraytime[$i], 'y' => $arraytime[$i]);
}

echo json_encode($arr);

You're going to want to look at PHP's date function: php.net/manual/en/function.date.php

Uhm ye sure .. but i need to figure out how to display 140222 as 14:02:22 instead of 140,222

You'll want to use PHP's date function for that.

I'm happy to elaborate if you'd like, but can you mark this answer as accepted so the thread isn't left open?
