The gap in shot attempts as the game went on: how many more one team had taken than the other. The line is
above the middle and red while Dallas Stars had taken more, and below it and blue while
Columbus Blue Jackets had.
Each line climbs with every chance a team had: a small step for a shot from far out, a big one for a
dangerous chance. A dot is a goal. Expected goals adds up how likely each shot was to go in, judged by
where it was taken from, what kind of shot it was and whether it was a rebound. Blocked shots and the
shootout are not counted.
Before 2023-24 the NHL timed events less exactly, and differently from rink to rink, so expected goals for this season are rougher than for recent ones.
