Today we will see how to make a pie chart of graph design in PHP and javascript. We will use canvas.js for graph design.
Make a table in the database:- Table name military_table (id, countrye_name, country_budget)
Now make a page index.php
<?php
$conn = mysqli_connect('localhost','root','','test');
$sql = "SELECT country_name,country_budget FROM military_budget";
$result = mysqli_query($conn, $sql);
while($row = mysqli_fetch_assoc($result))
{
$dataPoints[] = array("Country"=>$row['country_name'], "y"=>$row['country_budget']);
}
?>
<!DOCTYPE HTML>
<html>
<head>
<script>
window.onload = function()
{
var chart = new CanvasJS.Chart("chartContainer", {
animationEnabled: true,
subtitles: [{
text: " Year 2020-21"
}],
data: [{
type: "pie", // bar,doughnut,funnel,pyramid
yValueFormatString: "#,##0.\"\"",
indexLabel: "{Country} ( ${y} billion)",
dataPoints: <?php echo json_encode($dataPoints, JSON_NUMERIC_CHECK); ?>
}]
});
chart.render();
}
</script>
</head>
<body>
<h1 style="text-align:center;color:gray">Pie Chat Data using PHP/MYQL</h1>
<h2 style="text-align:center;color:green">Country by Military Budget ( In Billion Dollar )</h2>
<div id="chartContainer" style="height: 370px; width: 100%;"></div>
<script src="https://canvasjs.com/assets/script/canvasjs.min.js"></script>
</body>
</html>
