if I understand right what you mean you might want to take a look at the example project in Polarion ALM - the Dashboard page is actually a Wiki page so you can reuse the constructs seen there.
Sample Dashboard: http://almdemo.polarion.com/polarion/#/ ... /dashboard
(you may need to sign up for an account first)
Source code of the Wiki page: http://almdemo.polarion.com/polarion/#/ ... ileContent
You can see there how "facts" from "fact bases" are displayed in the page as percentage bars. For details on how to fill and use fact bases please see the Help in Polarion ALM.
Also you might want to check out POP, the Polarion extension portal: http://extensions.polarion.com/polarion/extensions/
Maybe there is some extension that you could use out of the box or as a source of inspiration.
