//////////////////////////////////////////////////////////////////// // 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); // //////////////////////////////////////////////////////////////////// #include "TROOT.h" #include "TStyle.h" #include "TPaveText.h" #include "TText.h" #include "TLatex.h" #include "TColor.h" #include "TSystem.h" #include "TStreamerInfo.h" #include <iostream> #include <cstdlib> using namespace std;
