I think it would help if you would write in English. Here is what Google Translate got from the above:

I am a little unsure what you are asking. If you want help getting started using Graph, I suggest you just start the program and try using it. The examples installed with Graph should give you some tips about what can be done and how.
The help file installed with Graph will also provide a lot of information. The Beta version of Graph 4.4 has a help file in Spanish.
If you have any specific questions you can always ask here.
