Centering axis title with use of TF1?

ROOT
1

What would be the command to put in my .rootstyle.C file in order to have all my graphs automatically updated with an axis (X & Y) title in the middle of the axis?

The following doesn’t work for me:

In the style sheet: MatthieuStyle->SetTextAlign(22);

Or directly in the code:
TCanvas *c5 = new TCanvas(“c5”,"",0,0,800,600);
c5->cd();
TLegend leg2= new TLegend(0.6,0.1,0.8,0.4);
TF1 neut_plot_recEne1 = new TF1(“neut_plot_recEne1”,neutralino_rate,1.0,200,3);

neut_plot_recEne1->SetParameter(0,10);
neut_plot_recEne1->SetParameter(1,xsec);
neut_plot_recEne1->SetParameter(2,244);
neut_plot_recEne1->SetLineColor(kBlack);
neut_plot_recEne1->SetLineStyle(9);
neut_plot_recEne1->Draw();

neut_plot_recEne1->GetXaxis()->SetTitle(“Fluorine Recoil Threshold Energy (keV)”);
neut_plot_recEne1->GetYaxis()->SetTitle(“Event Rate (kg^{-1}d^{-1})”);
neut_plot_recEne1->GetXaxis()->CenterTitle(true);
neut_plot_recEne1->GetYaxis()->CenterTitle(true);

det71RecEnedata->Draw(“pSAME”);
det72RecEnedata->Draw(“pSAME”);

leg2->AddEntry(neut_plot_recEne1,“10GeV”,“l”);
leg2->AddEntry(neut_plot_recEne2,“30GeV”,“l”);
leg2->AddEntry(neut_plot_recEne3,“100GeV”,“l”);
leg2->AddEntry(det71RecEnedata,“Det 71 Data”,“p”);
leg2->AddEntry(det72RecEnedata,“Det 72 Data”,“p”);

gPad->SetLogx(1);
c5->Modified();
c5->Update();
c5->SaveAs(“fig_Count_Rate_71_72_WIMP_Response_recEne.png”);

I’ve spent all day looking for this but to no avail.

Thanks

To center the Y (and X) axis tithe on a given histogram (hpx) do:

hpx->GetYaxis()->CenterTitle(true);

There is no global setting for that.

It’s all good, I found a solution…

The reason why the code below
(
neut_plot_recEne1->GetXaxis()->CenterTitle(true);
neut_plot_recEne1->GetYaxis()->CenterTitle(true);
)

didn’t work is because I added “gPad->SetLogx(1);” after “CenterTitle(true)”.

If you put “gPad->SetLogx(1);” before “CenterTitle(true)” everything works fine!
