Show most read post during last 30 days

Hi,
I’m trying to show up the most read posts that were most read in the last 30 days. Plugin allows you to view only the data of entries published in the last X days.

How can I change the plugin to display most read posts from last 30 days, but containing all the entries on the site?

Thanks
