'Struggling with indexes in array php

Fetching json data from rapidapi and trying to put it into a canvasjs chart. I belive the problem why my chart doesnt print is because the array that i create doesn't have the right indexes. My array has the index 0 on each element which the desired has not, it has indexes 0-13.

Otherwise canvasjs won't accept the input into the chart. My out put:

Solution 1:^[1]

As stated in the comments, the value of the $mergedCases and $mergedDeaths arrays are being overwritten on each iteration, causing the resulting $dataPoints to be invalid. To resolve the issue, the index of the array needs to be incremented.

The debugging call of print_r($dataPoints); inside the iteration of the $array['response'] data, was showing you the individual array value as opposed to the desired final array result to be passed to canvas.js.

Array ( [0] => Array ( [z] => 219 [x] => 14165 ) ) 
Array ( [0] => Array ( [z] => 131 [x] => 12901 ) )

As opposed to the desired:

Array ( 
    [0] => Array ( [z] => 219 [x] => 14165 )
    [1] => Array ( [z] => 131 [x] => 12901 )
)

Additionally, you are also overwriting foreach ($result as $key => $value) in your nested foreach loops, to resolve the issue use different variable names for them such as foreach($deathArray as $k => $v). However, creating an array of the individual properties in $countryArray = array($value['country']);, $deathArray = array($value['deaths']); $caseArray = array($value['cases']); is redundant, since they do not need to be iterated over.

As you are not utilizing the individual $mergedCases or $mergedDeaths arrays, refactor your approach to append to the $dataPoints array using the parent index $key instead to maintain the array placement.

Example

$array = json_decode($response, true);
$result = $array['response'];
$dataPoints = [];
$phH = $phL = $highest = $lowest = null;
foreach ($result as $key => $value) {
    $dataPoints[$key] = [
       'x' => $cases = $value['cases']['total'],
       'y' => $deaths = $value['deaths']['total'],
    ];
    if (null === $phH || $highest < $deaths) {
        // determine highest point
        $highest = $deaths ? : 0;
        $phH = $key;
    }
    if (null === $phL || $lowest > $deaths) {
        // determine lowest point
        $lowest = $deaths ? : 0;
        $phL = $key;
    }
}

// assign highest and lowest points
$dataPoints[$phL]['indexLabel'] = 'Lowest';
$dataPoints[$phH]['indexLabel'] = 'Highest';

var_export($dataPoints);

<table class='styled-chart' id=''>
    <thead>
