Hello Peter!

this article should indicate you how: http://www.joomlathat.com/documentation/content-statistics/create-graphic-statistics

and simply, in the options, you just need to select "virtuemart" for the content provider, and whatever data you want to display (number of orders, etc)

Hi, thanks but unfortunately it's not working yet. I get some output for 1) Product views or 2) category views but the rest, e.g. 3) Product purchases or 4) Orders, remains empty. All I get is a flat line. I have VirtueMart 3.0.9, is the module compatible with this?

yes, it's compatible.. there must be something we're missing.

if you can send me access to the site at support@ joomlathat.com, I'll take a look at it.
