This class is needed by JsMVA, and it's a helper class for tracking errors during the training in Jupyter notebook.
Itâ€™s only initialized in Jupyter notebook context. In initialization we specify some title, and a TGraph will be created for every title. We can add new data points easily to all TGraphs. These graphs are added to a TMultiGraph, and during an interactive training we get this TMultiGraph object and plot it with JsROOT.

void TMVA::IPythonInteractive::Init  (  std::vector< TString > &  graphTitles  ) 
This function gets some title and it creates a TGraph for every title.
It also sets up the style for every TGraph. All graphs are added to a single TMultiGraph.
