Pggraph

PG Graph 2 plots its graphs using one of two methods:

• Backends are plotted absolutely, by number of backends at any given time.
• All other plot deltas between now() and now()-interval. FX: * at 12:20, the value is 5305219037, and at 12:30, the number is 5308526897. This is a delta of 3,307,860, which is then plotted. * Had the value at 12:30 not increased, it would have been a delta of 0, or no commits(in this case) being done.
