Retrieve data from mysql by php to create flot graph

flot, php

Solution

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>
