Hi Christina,

It seems that there was a typo ion the docs.  The parameter is actually 
called TranspBG in the source code and not TransBG. I have fixed the 
docs on the website at

Can you please try TranspBG=1 and see if that works for you?


P.S. Please use the owtchart-users list for future questions since 
others on the list may have the same question or know the answer:
I have CC'd this reply to the list.
