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.

void TMVA::IPythonInteractive::AddPoint	(	Double_t	x,
		Double_t	y1,
		Double_t	y2
	)

This function is used only in 2 TGraph case, and it will add new data points to graphs.

Parameters

[in]	x	the x coordinate
[in]	y1	the y coordinate for the first TGraph
[in]	y2	the y coordinate for the second TGraph

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

[in]

dat

vector of data points. The dat[0] contains the x coordinate, dat[1] contains the y coordinate for first TGraph, dat[2] for second, ...
