the variable data val1 is not coming in the trend.
javascript code
var val1;
$(function () {
getData();
function getData()
{
xhttp = new XMLHttpRequest();
xhttp.onreadystatechange = function () {
if (this.readyState == 4 && this.status == 200) {
var dataSet = JSON.parse(xhttp.responseText);//deserialization
val1 = dataSet[0].fcnt;
}
};
xhttp.open("GET", "rest api url", true);
xhttp.setRequestHeader("Authorization", "BASIC dmlEyMw==");
xhttp.send();
}
// Get context with jQuery - using jQuery's .get() method.
var areaChartCanvas = $('#areaChart').get(0).getContext('2d')
// This will get the first returned node in the jQuery collection.
var areaChart = new Chart(areaChartCanvas)
var areaChartData = {
