Hi, I have to draw this kind of graphs on the computer:

I tryed to plot the graph of the function in mathematica, export it into .wmf file and then add some of the lines and labels in AutoCAD.
Is there any more effective way?
Another thing is - I would like to use some Latex-like font for the labels, but I don't know which.
Thanks for any help.

Most of the time I just use Excel. You can do a lot of annotations, fonts, etc.. It does depend on your input on how easy it is to produce the plots though. I have done some pretty complicated plots though.
