#### Topic: Generating a .grf (for testing trends)

Hello,

Right now, I am in the middle of a mathematical investigation of the properties of systems of linear equations. (Yes, that is high school.) I would like to use Graph to highlight any graphical patterns of certain families of linear functions; however, I am way too lazy to input each and every new function with a new gradient manually.

Since I am able to generate the function formulae mechanically, I naturally stumbled upon the option to generate a .grf file and then just let Graph display it. Granted, I can do that now; however, for purposes of presentation, it would be nice to be able to differentiate between different functions at first sight.

Despite looking through the documentation and this forum fairly thoroughly, I am unable to find properties and their assorted values in .grf files. The questions I am asking is therefore this:

1) What values are allowed for properties Style, Color in the areas assigned for definitions of functions?

2) Are there any other properties influencing the visuals of a function?

Thanks in advance for considering me

S.
