Here is an improvement/bug fix for your WordPress plugin.
in the analytics360.php file...
replace all instances of ABSPATH.PLUGINDIR with WP_PLUGIN_DIR.
No need to complicate it the way you do, and it's also not best practice to hard-code it because ppl can change the name of the wp-content directory.
I did, and your plugin broke!
Hence this "best practice" approach.
