Guys, Ive been working on that too.. I got my datas from database and send
them to chart but I see a blank page when I try it in WAMP... no errors but
there is not something to see.
code:
<html>
<head>
<script type="text/javascript" src="
https://www.google.com/jsapi";></script>
<script type="text/javascript">
google.load("visualization", "1", {packages:["corechart"]});
google.setOnLoadCallback(drawChart);
function drawChart() {
var data = google.visualization.arrayToDataTable([
<?php
$con = mysql_connect("localhost:3306", "reverse", "");
if (!$con) {
die('Could not connect: ' . mysql_error());
}
mysql_select_db($database, $con);
$result = mysql_query("SELECT * FROM `test` LIMIT 0 , 30");
$output = array();
while($row = mysql_fetch_array($result)) {
// create a temp array to hold the data
$temp = array();
// add the data
$temp[] = '"' . $row['Temp'] . '"';
$temp[] = '"' . $row['Humidity'] . '"';
$temp[] = '"' . $row['Light'] . '"';
// implode the temp array into a comma-separated list and add to the
output array
$output[] = '[' . implode(', ', $temp) . ']';
}
// implode the output into a comma-newline separated list and echo
echo implode(",\n", $output);
mysql_close($con);
?>
]);
var options = {
title: 'Selfcheck Stats'
};
var chart = new
google.visualization.LineChart(document.getElementById('chart_div'));
chart.draw(data, options);
}
</script>
</head>
<body>
<div id="chart_div" style="width: 900px; height: 500px;"></div>
</body>
</html>
