5c09ff70 1// Macro compareFlowResults.C is used to show a set of predefined plots with results
2// of flow analysis. It's usage is very simple: If you have output root file of flow
3// analysis <outputFileName> in directory <dir>, simply copy the macro in <dir> and
4// execute it. Remarks:
5// 1.) Make sure that the 'TString analysisType' bellow is the same as the one which
6// was used in the analysis which have produced the <outputFileName>;
7// 2.) Abbreviations used here are: RF = Reference Flow, RP = Reference Particles,
8// POI = Particles Of Interest;
9// 3.) To modify cosmetics of each plot change default settings in function which
10// have produced that plot. Example: If you want to modify marker colors in
11// the plot for reference flow, modify array Int_t methodMarkerColor[nMethods]
12// in the function PlotReferenceFlow().
