TMVA::IPythonInteractive Class Reference

This class is needed by JsMVA, and it's a helper class for tracking errors during the training in Jupyter notebook.

It’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.

AddPoint() [2/2]

void TMVA::IPythonInteractive::AddPoint

(

std::vector< Double_t > &

dat

)

This function can add data points to as many TGraphs as we have.

Parameters
