[ROOT] How to change the text in the header?

Hi,
Please explain how to change in an existing root file the text ``Graph''
(in the header window) into something else. The sequence
clear text, inserting true and inserting text ``bla''
does not work. I always get the old text ``Graph'' back.
Please help. Thanks,
            Klaus Freudenreich
