Method Chaining

[Velocities]

At the end of stocker/stocker/predict.py, you are applying multiple functions to plt. As long as the functions return self, you should be able to chain the methods. For example:
Instead of this:
word = 'hello'
word.upper()
word.lower()
print(word)
You could do this:
word = 'hello'
word.upper().lower()
print(word)
This is a weird example, but just an idea.
