I'm trying to use custom variables to track client side software version number. It working great so far: the value of the user scoped custom variable is being sent to GA and I'm able to see the result on my dashboard.
The only problem is that I can't find how to get only the last value submitted by a user and have a pie chart diagram showing the proportions of users running each version.
Is this even possible?
BTW I'm still using ga.js through Pyga Python module so using Dimensions is out of question.
