how to show ng-repeat in angular - angularjs

Question

I have JSON list data from API, it called by
$scope.link = globalVar.folderAPI+"/web/data.php";
$http.get($scope.link).then(function(response){
$scope.listDataitem = response.data.respone;
})
i want to show the data period to chart
this bellow I've wrote, but it still cannot appear, how to make the data display on chart, how can I parse the data to chart script part
<script>
var ctx = document.getElementById("myChart");
var myChart = new Chart(ctx, {
type: 'bar',
data: {
labels: [<div ng-repeat=" x in listDataitem "> {{ x.period }} </div>],
datasets: [{
data: [<div ng-repeat="y in listDataitem"> {{ y.sales}} </div>],
backgroundColor: [
'rgba(255, 99, 132, 0.2)',
'rgba(54, 162, 235, 0.2)',
'rgba(255, 206, 86, 0.2)',
'rgba(75, 192, 192, 0.2)',
'rgba(153,102,255,0.2)',
'rgba(255, 159, 64, 0.2)'
],
borderColor: [
'rgba(255,99,132,1)',
'rgba(54, 162, 235, 1)',
'rgba(255, 206, 86, 1)',
'rgba(75, 192, 192, 1)',
'rgba(153, 102, 255, 1)',
'rgba(255, 159, 64, 1)'
],
borderWidth: 1
}]
},
options: {
scales: {
yAxes: [{
ticks: {
beginAtZero: true
}
}]
}
}
});

You can try redraw your chart every time your API will be called.
$scope.link = globalVar.folderAPI+"/web/data.php";
$http.get($scope.link).then(function(response) {
$scope.listDataitem = response.data.respone;
let myLabels = [];
let myDataset = [];
for(let i = 0; i< $scope.listDitaitem); i++) {
myLabels.push($scope.listDitaitem[i].period);
myDataset.push($scope.listDitaitem[i].sales);
}
var ctx = document.getElementById("myChart");
var myChart = new Chart(ctx, {
type: 'bar',
data: {
labels: myLabels,
datasets: [{
data: myDataset,
backgroundColor: [
'rgba(255, 99, 132, 0.2)',
'rgba(54, 162, 235, 0.2)',
'rgba(255, 206, 86, 0.2)',
'rgba(75, 192, 192, 0.2)',
'rgba(153,102,255,0.2)',
'rgba(255, 159, 64, 0.2)'
],
borderColor: [
'rgba(255,99,132,1)',
'rgba(54, 162, 235, 1)',
'rgba(255, 206, 86, 1)',
'rgba(75, 192, 192, 1)',
'rgba(153, 102, 255, 1)',
'rgba(255, 159, 64, 1)'
],
borderWidth: 1
}]
},
options: {
scales: {
yAxes: [{
ticks: {
beginAtZero: true
}
}]
}
}
});
})
