[ROOT] TF1::RejectPoint and chi^2 in stats box

Hi,
fitting histograms with a non-contigous function via TF1::RejectPoint
works rather well, but for me it seems that the chi^2 that is shown in the
statistic box ignores the rejection. I tried to get the chi^2 directly
after the fit via

TF1* fitFunc = ...   // my TF1 defining the function
TF1* histToFit = ... // the hist that I fit
histToFit->Fit(fitFunc, "EMBRI");
TVirtualFitter::Fitter(histToFit)
    ->Chisquare(fitFunc->GetNpar(), fitFunc->GetParameters())

but that gives the same result which is also printed on screen as FCN
while fitting:

FCN=761.11  FROM MINOS     STATUS=SUCCESSFUL    804 CALLS <snip>


How can I get the 'real' chi^2?

Cheers

	Gero
