Hi i am trying to retrieve data from mysql database to create flot graph can anyone walk me through this procedure or give me an idea of what to do thanks
You probably want something like this. I haven't used flot but I looked at the example here.
<?php
//create array of pairs of x and y values
$dataset1 = array();
while ($row = mysql_fetch_assoc()) { //or whatever
$dataset1[] = array( $row['xvalue'], $row['yvalue'] );
}
?>
<script type="text/javascript">
//put array into javascript variable
var dataset1 = <?php echo json_encode($dataset1); ?>;
//plot
$(function () {
$.plot($("#placeholder"), [ dataset1 ]);
});
</script>
