commit c3729a065931ff13898a8e98807c801bd33e5b99 Author: Damian Johnson atagar@torproject.org Date: Sun Nov 9 18:19:22 2014 -0800

Switching graph intervals back to an enum

This isn't a revert, but rather moving the interval back into the panel in a way that'll make this easier to maintain. This lets us do all config validation in the conf_handler(). That's what it's there for. ;) --- arm/config/attributes.cfg | 9 ---- arm/graph_panel.py | 108 ++++++++++++++++++++------------------------- arm/menu/actions.py | 6 +-- 3 files changed, 51 insertions(+), 72 deletions(-)
