# ################################## # # 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); # ##################################
