Glad that you figured it out :)

You can also follow the below guidelines for more optimization:
1. If your page has dynamic charts, update chart options and re-render and don’t instantiate / create new chart on every update.
2. If you are populating data from JSON or CSV using AJAX, instantiate chart once and update data within AJAX request and do not instantiate / create new chart within every AJAX request.
