As shown in our book (blatant plug), if you put your loop "ForEachMember" in a macro, then it will perform all of your iterations before sending your need object to Image or Plot.

My question thus is:

- How can I apply Replace to each field in a group?

Or, more general:

- How can I apply any procedure (here Replace) to each member (here a
  field) in a group?

**************************************************************

Am I completely on the wrong track here?

(I tried to mess around with ForEachMember and Append, but this results
in iterations such that the plot is drawn several times, each time
with different y-data.)

Any hints are much appreciated. With many thanks in advance,

Hans
