Using the fetch api your code can look something like this:
fetch("someurl")//assuming get request, you need post then you need to pass a config object
.then(response => response.json())
.then(
json => ({
labels: json.months,//this depends on your json data
datasets: [
{
fillColor: "rgba(220,220,220,0.2)",
strokeColor: "rgba(220,220,220,1)",
pointColor: "rgba(220,220,220,1)",
pointStrokeColor: "#fff",
pointHighlightFill: "#fff",
pointHighlightStroke: "rgba(220,220,220,1)",
data: json.data//this depends on your json data
}
]
})
)
.then(
data => {
var context = document.querySelector('#graph').getContext('2d');
new Chart(context).Line(data);
}
)
If you want to support older browsers you need a polyfill
Examples of fetch api can be found here .
Your data can come from laravel restfull resource controllers
Can you Try this one buddy.
Controller
public function tracker()
{
$statistics = DiraStatistics::all();
labels = [];
data =[];
foreach ($statistics as $key => $statistic) {
labels= $statistic->date_access;
data = $statistic->question_asked;
}
return view('AltHr.Chatbot.tracker', compact('labels','data'));
}
js in blade.
<script type="text/javascript">
var data = {
labels: ['{{ $labels[0] }}', '{{ $labels[1] }}', '{{ $labels[2] }}', '{{ $labels[3] }}'],
datasets: [
{
fillColor: "rgba(220,220,220,0.2)",
strokeColor: "rgba(220,220,220,1)",
pointColor: "rgba(220,220,220,1)",
pointStrokeColor: "#fff",
pointHighlightFill: "#fff",
pointHighlightStroke: "rgba(220,220,220,1)",
data: ['{{ $data[0] }}', '{{ $data[0] }}', '{{ $data[0] }}', '{{ $data[0] }}']
},
]
};
var context = document.querySelector('#graph').getContext('2d');
new Chart(context).Line(data);
