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.
