# ##################################

|
# # PURPOSE:
|
|
# #
|
|
# # This file defines a reasonable style for (black-and-white)
|
|
# # "publication quality" ROOT plots. The default settings contain
|
|
# # many features that are either not desirable for printing on white
|
|
# # paper or impair the general readability of plots.
|
|
# #
|
|
# # USAGE:
|
|
#
|
|
# Simply add the line
|
|
# from LHCbStyle import LHCbStyle
|
|
# at the beginning of your root program (and make sure LHCbStyle.py is
|
|
# in a location accessible to the compiler). Then add the line
|
|
# lhcbStyle()
|
|
# somewhere at the beginning of your program
|
|
#
|
|
# SOME COMMENTS:
|
|
#
|
|
# Statistics and fit boxes:
|
|
#
|
|
# "Decorative" items around the histogram are kept to a minimum.
|
|
# In particular there is no box with statistics or fit information.
|
|
# You can easily change this either by editing your private copy
|
|
# of this style file or by calls to "gStyle" in your macro.
|
|
# For example,
|
|
# gStyle->SetOptFit(1011);
|
|
# will add some fit information.
|
|
#
|
|
# Font:
|
|
#
|
|
# The font is chosen to be 62, i.e.helvetica-bold-r-normal with
|
|
# precision 2. Font is of course a matter of taste, but most people
|
|
# will probably agree that Helvetica bold gives close to optimal
|
|
# readibility in presentations. It appears to be the ROOT default,
|
|
# and since there are still some features in ROOT that simply won't
|
|
# respond to any font requests, it is the wise choice to avoid
|
|
# ugly font mixtures on the same plot... The precision of the font (2)
|
|
# is chosen in order to have a rotatable and scalable font. Be sure
|
|
# to use true-type fonts! I.e.
|
|
# Unix.*.Root.UseTTFonts: true in your .rootrc file.
|
|
#
|
|
# "Landscape histograms":
|
|
#
|
|
# The style here is designed for more or less quadratic plots.
|
|
# For very long histograms, adjustements are needed. For instance,
|
|
# for a canvas with 1x5 histograms:
|
|
# TCanvas* c1 = new TCanvas("c1", "L0 muons", 600, 800);
|
|
# c1->Divide(1,5);
|
|
# adaptions like the following will be needed:
|
|
# gStyle->SetTickLength(0.05,"x");
|
|
# gStyle->SetTickLength(0.01,"y");
|
|
# gStyle->SetLabelSize(0.15,"x");
|
|
# gStyle->SetLabelSize(0.1,"y");
|
|
# gStyle->SetStatW(0.15);
|
|
# gStyle->SetStatH(0.5);
