I'm having problems with SetFillStyle

ROOT
1

Hello everyone,

TH1F *h1 = new (...); h1->SetFillStyle(3013);

TH1F *h1 = new (...); h1->SetFillColor(kRed);

The first code doesnt work, while the second one does… Does anyone have a clue?

Thanks

Andrea

Hmm, I guess, it’s quite difficult to notice white hatches on a white background :laughing: So, probably it works but you did not realise that :slight_smile:

Yes indeed, i was still trying to reproduce your code when i noticed it! #-o

Thanks a lot!

P.S. I thought Black was the default color, White is a bit misleading.
