Embarrassingly, I'm not quite sure what you mean. Care to elaborate?
This is a keychart. It's a technique created by Disney animations, and it used by almost all professional animation studios (including Pixar/Dreamworks, those people who make short animations on YouTube, anime studios etc etc). A really good overview is here: http://www.brianlemay.com/Pages/animationschool/animation/lipsyncbook/timingcharts.html
Basically, they're guide to help you know exactly how many frames you need to draw for a smooth animation.
There are three types of animation (the pipes represent frames):
1) Linear
|-------------|-------------|
2) Ease In/Accelerating
|---|---|-----|-------------|
3) Ease Out/Decelerating
|-------------|------|---|--|
Linear means that a motion remains constant. Ease In/Out is the start or end of a motion.
Basically what you do is you draw a chart on top of each frame you draw. You draw the start and end of a motion (the key frames), and you add these keys as big lines to your chart (name them A and B). You then add an in-between (the middle frame), and you put a smaller line in the center of your chart (name this one C). Then, in order to help the audience see the direction of your work and add flow, you add keys that either ease-in or ease-out. You add small lines for each one, and continue to name them in alphabetical order.
If you like, I can show you an example I made.
