[ROOT] stats for multiple histos

I'm trying to draw two different histograms on the same canvas and I 
would like to have the statistics box visible for both. For TH1F 
histograms xyt0 and xyt0c:

root [25] xyt0->Draw();                                       
root [26] xyt0c->Draw("sames");                                                         

Will draw both histograms, but the stats box of the second covers the 
stat box of the first. Following the instructions to move the box from 
the THistPainter::Paint documentation:

root [27] TPaveStats *st = 
(TPaveStats*)xyt0->GetListOfFunctions()->FindObject("stats") 
root [28] st->SetX1NDC(1)                                                                 
Error: illegal pointer to class object st 0x0 112  
FILE:/tmp/fileKzjdSx_cint LINE:1
*** Interpreter error recovered ***
root [29] 

How can I move one of the statistics boxes so both are visible?
