Filter Piwik by Author

Dear Users and Experts,

I would be very grateful for your help:
I would like to filter Piwik by Authors of posts (Wordpress). The website is being published with many posts by different authors and I would like to show all the visits or page views of one author´s posts in one go.

Is this possible with the Custom Dimensions Plugin? I found this on the net, but cannot get it running. Maybe you can help me install it with your expertise?

Tx and Best,

Nobody? Custom Dimensions?

Yes, Custom dimensions: Custom Dimensions - Analytics Platform - Piwik
