Disk Usage Report SSMS - query to obtain same info

I would like to have a query that obtains the same info as in the **Disk Usage** report, section **data/Log files autogrowth/autoshrink events** I would like to build a custom monitoring report but i could not find where this report comes. the only thing I could find is that this info comes from: sys.fn_trace_gettable but i don't know what field or joins I must do to have the same functionality as the report above. EDIT: i need these fields, also the size of the growth (for analytical purposes) thanks for your help.
