void TStatToolkit::CombineArray ( TTree *  tree,
TVectorD &  values 
)

Collect all variables from the last draw in one array.

It is assumed that the Draw function of the TTree was called before if e.g. Draw("v1:v2:v3") had been called, then values will contain the concatenated array of the values from v1,v2 and v3. E.g. if the v1[0..n], v2[0..n], v3[0..n] then values[0..3n] = [v1, v2, v3]

Parameters
[in]treeinput tree
[out]valuesarray in which to summarise all 'drawn' values

const char *  var,
const char *  selection,
const ENormType  normType,
const Bool_t  normaliseToEntries = kFALSE,
const Double_t  pvalue = 1. 
)

Calculate the distance of the values selecte in tree->Draw(var, selection)

If var contains more than one variable (separated by ':' as usual) the arrays are concatenated:
E.g. if var="v1:v2:v3", then the norm of the the concatenated array of the values from v1,v2 and v3 will be calculated:
This means if the internal tree arrays for each variable are v1[0..n], v2[0..n], v3[0..n] then the norm of vx[0..3n] = [v1, v2, v3] is calculated.

Parameters
[in]treeinput tree
[in]varvariable expression for the tree->Draw()
[in]selectionselection for the tree->Draw()
[in]normTypenorm to use for calculating the point distances
[in]normaliseToEntriesdivide the norm by the number of eleements ('average norm')
[in]pvaluep-value for the p-norm (ignored for other norm types
Returns
calculated distnace

TMultiGraph * TStatToolkit::MakeStatusMultGr ( TTree *  tree,

Int_t  igr = 0 
)

Compute a trending multigraph that shows for which runs a variable has outliers. format of expr : varname:xaxis (e.g. meanTPCncl:run, but 'varname' can be any string that you need for seach-and-replace) format of cut : char like in TCut format of alias: (1):(statisticOK):(varname_Warning):(varname_Out)[:(varname_PhysAcc):(varname_Extra)]

function MakeGraphSparse() is called for each alias argument, which will be used as tree expression. each alias argument is supposed to be a Boolean statement which can be evaluated as tree expression. the order of these criteria should be kept, as the marker styles and colors are chosen to be meaningful this way! 'statisticOK' could e.g. be an alias for '(meanTPCncl>0)'. if you dont need e.g. a 'warning' condition, then just replace it by (0). in the alias, 'varname' will be replaced by its content (e.g. varname_Out -> meanTPCncl_Out) note: the aliases 'varname_Out' etc have to be defined by function TStatToolkit::SetStatusAlias(...) counter igr is used to shift the multigraph in y when filling a TObjArray.

Parameters
tree- tree containing data to be plot
expr- string <variablearray>:<tagID>:<variablearrayError> <variablearray>="var0; ...; varN <variablearrayError>="err0; ...;errN"
alias- Boolean statement which can be evaluated as tree expression
igr- counter used to shift the multigraph in y when filling a TObjArray Example usage
To create the Status Bar, the following is done in principle.
( example current usage in $ALICE_ROOT/PWGPP/TPC/macros/drawPerformanceTPCQAMatchTrends.C and ./qaConfig.C. )
TStatToolkit::SetStatusAlias(tree, "meanTPCncl", "", "varname_Out:(abs(varname-MeanEF)>6.*RMSEF):0.8");
TStatToolkit::SetStatusAlias(tree, "tpcItsMatchA", "", "varname_Out:(abs(varname-MeanEF)>6.*RMSEF):0.8");

void TStatToolkit::RebinSparseGraph ( TGraph *  graph0,
TGraph *  graph1,
Option_t *  option = "" 
)

Remap bin labels for sparse graphs

Parameters
graph0- sparse graph to be rebinned
graph1- graph with "template x axis" (default)
option- TODO - implement merge option as an option

Example - remap sparse run list of QA.EVS graph to be like as in Logbook run list

AliExternalInfo info; tree = info->GetTree("QA.TPC","LHC15o","pass1","Logbook;QA.TPC;QA.EVS")
graph = TStatToolkit::MakeMultGraph(tree,"","Logbook.run;QA.EVS.run:run","run>0","21;21","2;4",1.0,1,4,0);
graph1 = (TGraph*)graph->GetListOfGraphs()->At(0); graph0 = (TGraph*)graph->GetListOfGraphs()->At(1);
//
TStatToolkit::RebinSparseGraph(graph0,graph1,"");

void TStatToolkit::RebinSparseMultiGraph ( TMultiGraph *  multiGraph,
TGraph *  graphRef 
)

Rebin sparse MultiGraph to have the same granularity of x axis as in reference graphRef

Parameters
multiGraph- multiGraph to remap
graphRef- reference graph

Used e.g to remap graphs in case of missing measurement in one of the sources

  • e.g Logbook run list for period LHC15o is longer than run list for the QA.EVS and QA.TPC "pass3_lowIR_pidfix"
AliExternalInfo info; tree = info->GetTree("Logbook","LHC15o","pass3_lowIR_pidfix","Logbook;QA.TPC;QA.EVS")
graph = TStatToolkit::MakeMultGraph(tree,"","Logbook.run;QA.TPC.run;QA.EVS.run:run","runDuration>600","25;21;24","1;2;4",1.5,1,4,0);
