                        var x = (new Date()).getTime(), // current time
                            y = Math.random();

                // generate an array of random data
                var data = [],
                    time = (new Date()).getTime(),
                    i;

                for (i = -19; i <= 0; i++) {
                    data.push({
                        x: time + i * 1000,
                        y: Math.random()
                    });
                }

Hi,

after i been searching for the highcharts, i hv been link to this tutorial which lead me to a sample for using highcharts with mysql data dyanamic inputs.

here is my sample code usage

[php]

Using Highcharts with PHP and MySQL

[/php]

The above is how we call highcharts and display it

[php]<?php
$con = mysql_connect(“localhost”,“root”,"");

if (!$con) {
die('Could not connect: ’ . mysql_error());
}

mysql_select_db(“highcharts_php”, $con);

$result = mysql_query(“SELECT * FROM highcharts_php”);

while($row = mysql_fetch_array($result)) {
echo $row[‘timespan’] . “\t” . $row[‘sellprice’]. “\n”;
}

mysql_close($con);
?> [/php]

this is how i get my x axis data.

there here is my another question.

i been wondering the data is display for the datetime is using highcharts interval time which is belongs to y axis. how am i able to get the time from mysql data???
