Hello,
I'm making TH1D's with fairly large numbers in the bins. After a certain size I get these warnings:
Warning in <TCanvas::ResizePad>: Inf/NaN propagated to the pad. Check
drawn objects.
Warning in <TCanvas::ResizePad>: canv height changed from 0 to 10.
and the histogram is not plotted.
The highest bin value that is plotted successfully looks to be around 6 x 10^65.
Is there a limit on the size of the Double_t that can be plotted in a histogram? It is certainly possible to assign much larger numbers to a Double_t, for example:
root [31] Double_t bignum = 1e300
root [32] bignum (Double_t)1.00000000000000005e+300
I'd appreciate any hints on how to work round this.
Thanks,
Roger
