            'graphUsersMonth'=>$graphUsersMonth,
            'graphArticlesMonth'=>$graphArticlesMonth,
        ]);
    }

instead of $graphUsersMonth = new Lavacharts; change that to $lava = new Lavacharts;

remove $graphArticlesMonth = new Lavacharts;

Then your datatables can be created like this: $dadosUsersGraph = $lava->DataTable(); and $dadosArticlesGraph = $lava->DataTable();

remove these two lines:

    'graphUsersMonth'=>$graphUsersMonth,
    'graphArticlesMonth'=>$graphArticlesMonth,

and pass $lava to your view instead.

Then in your view, instead of $graphUsersMonth->render and $graphArticlesMonth->render they should both be $lava->render
