Beats me. The code works fine right "out of the
box" for me and produces arrows with or without setchartoptions(). So, the
problem is not the code. Attached is a screen shot of your code. You
say that plotshapes() stopped working which indicates that it did work at one
point. Can you recall if you made any program changes (e.g.,
settings) since then? If not and if nobody has an idea, suggest
contacting support.
