Y axis label

ROOT
1

Hello rooters,
I wonder if it is possible to rotate clockwise of 90 degrees the labels on the Y axis of a TGraph or a TH1 because with the folllowing instruction it appears hard to read:

isto->GetYaxis()->SetTitle("#frac{P_{S}}{#hat{D_{NN}}}");

thanks
best regards

Dario

You can do:

Axis->RotateTitle()

but that will rotate the title by 180 degrees

To improve the readability you can also change the title offset:

Axis->SetTitleOffset(1.5);
