Can't get axes titles in TF1

Hello, I used the commands in my macro

f2->GetXaxis()->SetTitle("Ep (eV)");
	f2->GetYaxis()->SetTitle("Height");

but I don’t get the titles…

The first plot is f1. You should set the tite on f1.

...
	f1->Draw();
	f1->GetXaxis()->SetTitle("aaaa");
	f2->Draw("SAME");
...

Thank you @couet it works…I see that you just used
f1->SetTitle without the GetXaxis…but why did it work for you (You attached the pic) and not for me?

[couet]

Before you did:

f1->GetXaxis()->SetTitle("x title")
f1->SetTitle(); // this erase the X tile

… you can set the 3 titles in one go:

f1->SetTitle("title ; x title ; y title");
