In my case everything I wanted from root was to display "y:x". The default
way ROOT displays such a beast was exactly what I wanted. I was even not
interested in the created histogram. I just wanted to see "all" points
from the ntuple on the screen. Unfortunately, when I finally got proper
axises ... and there was the chance that I will see what I wanted ... I
was advised "*** Save data and exit application ***" instead.
(In the end I had to drop "Draw" and become familiar with "Process", but
it would make my life much easier if I was able to Draw something without
the risk that ROOT dies.)
