Notes:

A graph I made of the average number of days between air dates of several recent/current Western cartoons (not counting episodes aired the same date) to show how sparsely episodes of Gravity Falls are aired.
Characters used on the graph:
Wirt from Over the Garden Wall
Mordecai from Regular Show
Finn "the Human" Mertens from Adventure Time
Steven Quartz Universe from Steven Universe
Uncle Grandpa from Uncle Granpda
Gumball Tristopher Watterson from The Amazing World of Gumball
Leonardo from Teenage Mutant Ninja Turtles
Wander from Wander Over Yonder
Phineas Flynn from Phineas and Ferb
Robin from Teen Titans Go!
Korra from The Legend of Korra
Dipper Pines from Gravity Falls
