Hi, I have to draw this kind of graphs on the computer: http://img285.imageshack.us/img285/1690/image1nc4.jpg [Broken] http://img427.imageshack.us/img427/6483/image2it9.jpg [Broken].[/URL] 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.
