How can I make a better plot?

Hi, I have 5 sets of data and I want to write a script that reads my 5 matrices (1x21 double) and displays a single figure that plots the mean error (y) against the gain (x) in decibel. The output of my script should has:
- The lines for each segment should be displayed using a different color. With point where is the value on the segment.
- A legend should be included indicating wich line corresponds to wich segment
- Each segment should has his linear fit (courve fitting) in wich I can find the ratio between the axes
I think I have to use iteraction for a solution of this kind, but I'm not sure how.
These are my 5 data:
