Dear David, Nick, and Austin
Thank you very much for your suggestions! All sound very interesting.
I now started to implement Nick's solution with -gettoken-; so far it
works fine. I will think about support for weights (Austin, your guess
was correct: -collapse- is followed by -twoway bar- in my code.), as
well as support for "look of bar options" and "look of percentage
label" options.
Thanks again, and all the best,
Eva
