Hello, I have 2 questions:

1 - What is the best way to put some labels on a 2D chart like those one in red in my attachment? This red ones I used paint just as an example.\


2 - The horizontal axes, I couldnt find out how to give a better precision, I have only 2 divisions (0,1) but I want more like from -0.2, -0.1 ... 1.0 , 1.2...

Thank you in advance!
