Hi to all
i have a problem with a simple scattered chart: the x values (categories) are poorly managed with overlapping. I post you simple code (from a modified version of 33chartcreate-scatter.php). I've test this script with last version of PHPExcel. What is wrong??

Here is the code:
<?php

/** Error reporting */
error_reporting(E_ALL);
ini_set('display_errors', TRUE);
ini_set('display_startup_errors', TRUE);
date_default_timezone_set('Europe/London');

define('EOL',(PHP_SAPI == 'cli') ? PHP_EOL : '<br />');

date_default_timezone_set('Europe/London');
