I have a quite primitive question concerning the TFitter.
I’m using TFitter for a custom minimization and would now like to plot a contour of the results. In the documentation I found that TMINUIT provides this and so I tried to get the TMinuit member via the public TFitter method “GetMinuit()” (http://root.cern.ch/root/html/src/TFitter.h.html#yjpoRB)
This however just produces the error message
root  pt_fitter->GetMinuit() Error: Can't call TFitter::GetMinuit() in current scope (tmpfile):1: Possible candidates are... (in TFitter) *** Interpreter error recovered ***
Other public methods like
root  pt_fitter->GetCovarianceMatrix() (const Double_t*)0x15af560
work as intended. The minimization itself also worked, so the TFitter should be correctly initialized …
Is there something I’m missing?
Thanks in advance!
