Matching fonts in figures (.EPS) with font in main text

[Luke Lindsay]

I am using Lyx to write my thesis.  I have a number of figures in EPS 
format which are produced by various programs (Stata, Maple, Open office 
draw).  I would like the fonts in the figures to be consistent with the 
one used in the main body of the text, i.e. same font and size.  What is 
the best way to achieve this?  Ideally, I'd like to be able to change 
the font in used in the main document have font used in the figures 
updated automatically but I’m not sure if this is possible.
