3 | * Plotting macro for comparing offline- and HLT- ESD trees from | |
4 | * HLT-OFFLINE-GLOBAL-comparison.root produced using $ALICE_ROOT/HLT/QA/tasks/AliAnalysisTaskHLT.* | |
5 | * | |
6 | * Usage: aliroot drawGlobalESDHistograms.C++ in compiled mode | |
7 | * | |
8 | * It saves all canvases with the output histograms in a png and a ROOT file. | |
9 | * The second argument of the macro will produce individual files for all pads, | |
10 | * in case it is turned to kTRUE. | |
11 | * | |
