{////////////////////////////////////////////////////////////////////
// PURPOSE:
//
// This macro 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 readibility of plots.
//
// USAGE:
//
// Simply include the line
// gROOT->ProcessLine(".x $LHCBSTYLE/root/lhcbstyle.C");
// at the beginning of your root macro.
//
// 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);
//
