Thanks a lot for you help!

I wanted to move your code
* from an specific Stat-extension on ~/Kernel/System/Stats/. (where it 
works)
* to ~/Kernel/Module/SystemStats.pm (about line 170) to be executed on 
certain conditions

#--------------------------
             my $TitleArrayRef = shift (@Data);
             my $Title = $TitleArrayRef->[0];

my @NewData = ();
foreach my $Key1 (0..$#Data) {
     foreach my $Key2 (0..$#{$Data[0]}) {
         $NewData[$Key2][$Key1] = $Data[$Key1][$Key2];
     }
}
@Data = @NewData;

             my $HeadArrayRef = shift (@Data);
#--------------------------

This code seems not to be executed - why?
I also edited some other parts in SystemStats.pm but I couldn't 
recognize any changes in OTRS-behaviour - why?

One further problem:

My own statistics work fine with print output format,
but often apache-errors are sent to the client on graphical output:
Some combinations of graph-output-types and resolutions work, others don't.

apache-error-log contains:

Do you know this problem?

That sounds great!
