If you are going to make a lot of graphs, and keep doing this over your career, I'd strongly suggest you learn to use the free statistical program R, which can make publication quality graphics, write on them however you like, and export ot pdf, png, eps, or whatever. http://www.r-project.org. If you have trouble getting started, I have a tipsheet with explanations for things like "how to save a graph". http://pj.freefaculty.org/R look for Rtips.html
Paul, At last count, there were more than a dozen vector graphics applications available for linux. Some of them (e.g., IPE, jpicedt, tgif) are great for drawing various shapes; others (e.g., Gri and PSTricks) also include data plotting capabilities. R, of course, is a statistical data analysis language that incorporates plot generation, too. Depending on what is needed, the other applications may have a shorter, more shallow learning curve. Most of them produce .eps or .pdf as output so incorporation into LyX is smooth and easy. Rich -- Richard B.
