Label/title sizes with Divide(n,m,0)

ROOT
1

Hi,
The attached script plots twice the same histogram in a canvas. Since the X-axis is the same and I need it plotted just once, I did a Divide(1,2,0). What annoys me is that the text has a different size in the two histograms (labels, stat box,…). How to keep them similar without having to tweak all the offsets and sizes?
Thanks

Specify the various fonts in pixels instead of per cent of pad size

[code]{
gStyle->SetLabelFont(63,“x”); //font in pixels
gStyle->SetLabelSize(14,“x”); //font size in pixels
gStyle->SetLabelFont(63,“y”);
gStyle->SetLabelSize(14,“y”);
gStyle->SetStatFont(63);
gStyle->SetStatFontSize(14);
hpx = TH1F( “hpx”, “”, 100, -4, 4 );

for (int i=0;i<25000;i++){
float px = gRandom.Gaus();
hpx.Fill(px);
}

hpx.SetYTitle(“Some Title For This Axis”);
c1 = TCanvas(“c1”,"",10,10,700,700);
c1.Divide(1,2,0.001,0.001);
c1.cd(1);
hpx.Draw();
c1.cd(2);
hpx.Draw();
}[/code]

Thanks Rene, but it doesn’t merge the bottom X-axis of the top plot with the top X-axis of the bottom plot (which is the intention here) when you put 0.001 instead of 0 in the Divide(1,2,0). Reintroducing the 0 with your gStyle settings, the label sizes are still different.

I forgot to set teh title font/size/offset. Add teh following lines:

gStyle->SetTitleFont(63,"y"); gStyle->SetTitleSize(14,"y"); gStyle->SetTitleOffset(1.9,"y");

see all options in TStyle
