Pinpoint Pitching

[elway7751_PSN]

So we are in the second year of this and I use this exclusively, but I'm still not understanding it completely.
What exactly does every pice of info displayed mean?
For example when I throw a fastball, my line is green all the way, but anything offspeed I get a lot of yellow, either to fast or slow, but I feel I've done nothing different.
That is just a small portion of the different feedback you get.
Just trying to understand every part and how to get better at it.
