It's from an old role playing game called "Wild West". To figure out your chance of success on percentile dice, you take a ruler from the experience side and run in thru the CV value (Characteristic Value), then the percentage chance is given on either A,B, or C column.
The A scale is if the task is extremely hard.
The B scale is if the task is difficult.
The C scale is if the task is routine.

So I'm wondering what is this type of chart/graph called and how it's created?
