How to get the avarage score of specific post by post id

Yes of course, what kind of rating do you want to show?

The visitor vote of a post by that post’s id

Have you seen this post?

Or do you need to get only the average without the stars?

Yes, I want the average score only like 4.5 or 5. Is there any way to achieve it?

In the plugin dir, open file lib/yasr-shortcode-functions.php , go on line 250 (before the if statment) and add this

$shortcode_html = $medium_rating

Remember that if you do so yasr_visitor_votes will no show stars elsewhere
