Matt and Inez show Ms. Fileshare a bar graph of the bugs in different sections of the Cybrary. Inez eplains how to read the graph. Their graph shows that, contrary to Vermin Vexer's claims, there are a lot of bugs in the History section. Hacker shows his own graph that suggests the opposite: the number of bugs in the History section isn't a problem. Ms. Fileshare trusts Vermin Vexer's graph over Matt and Inez's graph.
Digit shows the CyberSquad two line graphs that illustrates how much power is being used vs. the time of day. The graph for the current day is different than that of a normal day, so the CyberSquad interprets the change and finds that something was causing intermittent power outages.
Jackie, Matt, and Inez print out a graph that shows the distance in cyber miles that Hacker traveled in relation to the time he spent traveling. They analyze the graph to guess what Hacker was doing and to where he traveled.
The residents of Sensible Flats have no more water in their resevoir and are trying to discover why the water levels have declined. The CyberSquad asks for historical records of the water level, and Rudy provides records of the last 25 days to the group. Inez, Matt, and Jackie think about how to use the dates to tell a story and decide that graphing the water levels day-by-day would work. The CyberSquad creates a line graph on the side of the tank and explains how to read the graph to the residents.
