[ROOT] Strange inconsistency in TH1::Fit()

Hi,

for some reason the O option in TH1::Fit() doesn't seem to work.
The following code shouldn't draw the histogram, but it does.
Strangely, the source code (viewed through the class category
documentation) seems to be OK?


TF1 *theory = new TF1("theory", "expo(0)", 0, 1);    
theory->SetParameters(1, -1);
TH1D *data = new TH1D("data", "raw data", 20, 0, 1);    
data->FillRandom("theory", 500);
TF1 *f = new TF1("f", "pol3(0)", 0, 1);
data->Fit("f", "OQ");  // the histogram gets drawn!


Please send a reply also to my e-mail address.
