Loading 

xAccelChartInstance.data.datasets.forEach(function(dataset) {
    dataset.data.push(data['xA']
});

this should work.

Hello Dear,

This is very helpful program, I was trying to display your sample by slightly changing in data loading part, but it is not working. Would you please take a look?
Here I am getting a json array data and passing those data to your addData function but nothing is displaying in the chart.
I have written a ASP.Net core application to display the charts.

function updateData() {
console.log("Update Data");
$.ajax({
url: '/Home/GetServerPerfData',
type: 'POST',
dataType: 'json',
contentType: 'application/json',
success: function (icpdata) {
icpdata.forEach(obj => {
addData(obj);
})
}
});
setTimeout(updateData,updateInterval);
}
updateData();
Rest of the codes kept exactly the same as your one above...

This is my json data...
