Chart Notes
Color is required to view the charts properly!
The normalized scale in Chart 2 is different from all other normalized scales.
This is because the scale was re-normalized when the battery centroid was separated.
Data from Charts 2 and 5 are from before the battery centroid was separated.
Data from Charts 3, 4, and 6 are from after the battery centroid was separated.
In Charts 5 and 6, the x-axis indicates the actual item observed.
The count on the y-axis is the number of times the Quagent identified an item.
So for the 13 CBs observed, the Quagent identified 11 as CB, 1 as mitsu, and 1 as randal.
