I have been having arguments at work which divided the team on whether or not a data usage graph should start at 100% and decline to 0% showing whats available (option A). Or conversely, start at 0% used and increase showing what has been used (option B).
I was wondering if anyone had any research or opinions on this, as I haven't been able to find anything online... and the opinions are quite strong and polar within the team as to what 'feels' correct has caused and is still causing arguments.
EDIT: The context for this is for a user portal on an internet service provider website. So our company sells prepaid (and postpaid) data packages to users, and this graph would be used in the portal (or mobile app) for users to check there remaining data balance.
