What are the parameters for trackPageView method

I implemented the javascript piwikTracker.trackPageView(’/path/to/something’) and the data shows up in the reports in the page titles section. I can’t find in the documentation or forums what the parameters are for this method. I would like to have the data show up as a page view to a page located a ‘/path/to/something’ and not buried in the page titles section.

Use setCustomUrl() to fake the URL rather than the Page title

I’m trying to track button clicks and do not want to change the URL of the page that I’m on. Won’t that change what piwik tracks for the entire page? I do not want to do that. Just log a click event.
