How to limit the count of characters scrolling

Hi, I'm Vincent. I just know here is a very useful framework you did.
After testing, I'm confused about how to limit the count of characters scrolling.
For example , if now is "3456" and next number is "3489" , how to only scroll last two columns bus not scroll all?
