What are some common challenges when working with JPGraph in PHP?

One common challenge when working with JPGraph in PHP is setting up the correct permissions for the cache directory. If the cache directory does not have the proper permissions, JPGraph may not be able to save generated graphs, leading to errors or blank images. To solve this issue, make sure to set the correct permissions on the cache directory. 

// Set the correct permissions for the cache directory
$cacheDir = 'jpgraph_cache/';
if (!is_dir($cacheDir)) {
    mkdir($cacheDir, 0755, true);
}
chmod($cacheDir, 0755);
