is it possible to call the login macro to change the default behaviour of the TProfile histograms to have the error bars = spread instead of dividing it by sqrt(n)?
as a more general question: how can i change the default root options? is there a file or it’s all hard coded?
Some parameters controlling parameters like level of debug, default search path, etc
can be set in $ROOTSYS/etc/system.rootrc.
No options exist to change the default function argument values. And this is ON PURPOSE.
It will be a total chaos to see the result of a program changing depending if an input parameter is set or not in a resource file.
