I guess, I have to finally register at yet another list. ;)
Yes I know. It was really an attempt to group them logically since they
belong to the same piddle.
Ok, in principle I was right but I need a temporary variable to
construct the reference.
What works is:
$n=$mw->"$name\_plot1";
$mw->$n->dataSets->{set1}->change_data(0,1);
What does not work is
$mw->{$mw->"$name\_plot1"} -> ...
$mw->($mw->"$name\_plot1") -> ...
$mw->eval($mw->"$name\_plot1") -> ... # NiceSlice thinks $mw
contains a piddle and complains!
or any way do directly construct the method call.
