Hello,

I think you should do this in TikZ. You would not regret.

Attached is a simple setup for you get started. Compile the LaTeX file 
Fig01.tex and get the PDF of your figure first. Then, you can insert the 
PDF into your LyX file. If you want to change your figure, just compile 
the file again and LyX will do the job automatically for you.

My recommendation is: do not insert your code for figures (whether TikZ 
or not) into LyX as ERT box. Compile them separately and generate the 
figure PDF first. Then, insert the figure PDF into LyX. This will help 
you find errors and change the figures more easily without compiling 
whole LyX file. Also, it would be easier for LyX to compile the document.
