How to construct an Object with an Array inside, using Eloquent Laravel

Hello everyone, I need to build a array as follows for a plugin:

var data = [{
    "label": "Follows",
    "color": "#aad874",
    "data": [
        ["Seg", 50],
        ["Ter", 84],
        ["Qua", 52],
        ["Qui", 88],
        ["Sex", 69],
        ["Sab", 92],
        ["Dom", 58]
    ]
}, {
    "label": "UnFollows",
    "color": "#7dc7df",
    "data": [
        ["Seg", 13],
        ["Ter", 44],
        ["Qua", 44],
        ["Qui", 27],
        ["Sex", 38],
        ["Sab", 11],
        ["Dom", 39]
    ]
}];

I have tried several things like:

$staticWeeks = self::statisticstaWeeks();

$staticsDays['Follow']      = [];
$staticsDays['FollowBy']    = [];

if(count($staticWeeks) > 0):
foreach($staticWeeks as $weeks):
array_push($staticsDays['Follow'], $weeks->ins_sta_follow);
array_push($staticsDays['FollowBy'], $weeks->ins_sta_following);
endforeach;
endif;

$staticsDays['Follow'] = $diasFollow = [
    "Seg" => (!empty($staticsDays['Follow'][0]) ? $staticsDays['Follow'][0] : 0), 
    "Ter" => (!empty($staticsDays['Follow'][1]) ? $staticsDays['Follow'][1] : 0), 
    "Qua" => (!empty($staticsDays['Follow'][2]) ? $staticsDays['Follow'][2] : 0),
    "Qui" => (!empty($staticsDays['Follow'][3]) ? $staticsDays['Follow'][3] : 0), 
    "Sex" => (!empty($staticsDays['Follow'][4]) ? $staticsDays['Follow'][4] : 0), 
    "Sab" => (!empty($staticsDays['Follow'][5]) ? $staticsDays['Follow'][5] : 0), 
    "Dom" => (!empty($staticsDays['Follow'][6]) ? $staticsDays['Follow'][6] : 0)];

$staticsDays['FollowBy'] = $diasFollowBy = [
    "Seg" => (!empty($staticsDays['FollowBy'][0]) ? $staticsDays['FollowBy'][0] : 0), 
    "Ter" => (!empty($staticsDays['FollowBy'][1]) ? $staticsDays['FollowBy'][1] : 0), 
    "Qua" => (!empty($staticsDays['FollowBy'][2]) ? $staticsDays['FollowBy'][2] : 0),
    "Qui" => (!empty($staticsDays['FollowBy'][3]) ? $staticsDays['FollowBy'][3] : 0), 
    "Sex" => (!empty($staticsDays['FollowBy'][4]) ? $staticsDays['FollowBy'][4] : 0), 
    "Sab" => (!empty($staticsDays['FollowBy'][5]) ? $staticsDays['FollowBy'][5] : 0), 
    "Dom" => (!empty($staticsDays['FollowBy'][6]) ? $staticsDays['FollowBy'][6] : 0)];

$follow = [(object)[
    "label" => "Seguindo",
    "color" => "#aad874",
    "data"  => $staticsDays['Follow']
]];

$followBy = [(object)[
    "label" => "Seguidores",
    "color" => "#7dc7df",
    "data"  => $staticsDays['FollowBy']
]];

$result = array_merge($follow, $followBy);

return json_encode( $result );

And yet it does not return as I want.
