I know that many of you use xfig and I would like pointers to two tasks I need to do frequently: 1) draw S-, Z- or bell curves that are smooth and, in the latter case, symetrical and 2) enter Greek letters, math symbols and equations on the figure.
offen you get much more better results by using PSTricks http://pstricks.de Look for the Examples or the pst-plot
