Hi,

To work around the problem do:

	Double_t stats[10];
	for(int i=0;i<10;i++) { stats[i] = 0; };
	myhist->PutStats(stats); //effectively reset the statistics.
	
After executing this code, the histo will recalculate its statistics.

Cheers,
Philippe.

Hi,


After using  SetBins(), keeping the same number of bin but changing the 
axis limits, I get what I expected when i draw the TH1F but GetMean() 
always send the former value.

Why ?
How can I change that ?
