Problem labelling the x-axis

Hi all,

I am using these commands to label axis on TH2F

plot->GetXaxis()->SetTitle("Polar scattering angle (degrees)");
plot->GetYaxis()->SetTitle("Energy (keV)");

The y-axis labels fine, but the x-axis will not label. I get no error message. Also it will label from the editor.

Can anyone help


It all good now, no longer a problem thanks to Yus.
