i have an error when use chart on laravel - laravel

Question

Can someone can help me? I get an error when I try to use a chart.
Undefined variable: label (View: C:\xampp\htdocs\latihan_penjualan\resources\views\home.blade.php)
in 15bd1eeee4b4d1b903b52322d785ce7ce1ab31d2.php line 31
This is my controller:
public function index()
{
$kategori = DB::table('kategoris')->get();
$data = [];
$label = [];
foreach ($kategori as $i => $v) {
$value[$i] = DB::table('produks')->where('id_kategori',$v->id)->count();
$label[$i] = $v->nama;
}
return view('home');
$this->with('value',json_encode($value));
$this->with('label',json_encode($label));
}
And this is my view:
<div id="container" style="width: 100%;">
<canvas id="canvas"></canvas>
</div>
<script type="text/javascript" src="http://www.chartjs.org/dist/2.7.2/Chart.bundle.js"></script>
<script type="text/javascript" src="http://www.chartjs.org/samples/latest/utils.js"></script>
<script type="text/javascript">
var color = Chart.helpers.color;
var barChartData = {labels: {!! $label !!},
datasets: [{
label: 'Produk Per Kategori',
backgroundColor: color(window.chartColors.red).alpha(0.5).rgbString(),
borderColor: window.chartColors.red,
borderWidth: 1,
data: {!! $value !!},
}],
};
window.onload = function() {
var ctx = document.getElementById('canvas').getContext('2d');
window.myBar = new Chart(ctx, {
type: 'bar',
data: barChartData,
options: {
responsive: true,
legend: {
position: 'top',
},
title: {
display: true,
text: 'Grafik Data Produk'
}
}
});
};
</script>
I already declared the variable $label.
Thanks in advance.

Answer 1

return view('home')
->with(['value'=>json_encode($value),'label'=>json_encode($label)]);

Answer 2

Fix this part after return view('home');
public function index()
{
$kategori = DB::table('kategoris')->get();
$data = [];
$label = [];
foreach ($kategori as $i => $v) {
$value[$i] = DB::table('produks')->where('id_kategori',$v->id)->count();
$label[$i] = $v->nama;
}
return view('home')->with('value',json_encode($value))->with('label',json_encode($label));
}
