$(document).ready(function() {
var dataPoints = [];
var chart = new CanvasJS.Chart(“chartContainer”, {
animationEnabled: true,
exportEnabled: true,
theme: “light2”,
zoomEnabled: true,
title: {
text: “Attendance”
},
axisX: {
title: “Date”,
titleFontSize: 10
},
axisY: {
title: “Number of Present”,
titleFontSize: 10,
},
data: [{
type: “column”,
dataPoints: dataPoints
}]
});
function addData(data) {
var dps = data.attendance;
for (var i = 0; i < dps.length; i++) {
dataPoints.push({
x: new Date(dps[i][0]),
y: parseInt(dps[i][1])
});
}
chart.render();
}
$.getJSON(“http://localhost/fyp/results.json”, addData);
}
This would be my json file after running (results.json):
{“attendance”:[[1520809200000,”1″]]}
so, whenever i want to render the chart, i need to run “results.json” at the browse, then the chart will run according to the details in my mysql.
but i dont want to extra loading the “Results.json” file. i want it to render and get the data from mysql automatically. i dont know where do i wrong
