If you do not want to cut the labels on h1 and h2 you should do something like that:
{

TCanvas *c = new TCanvas("c","c",0,0,500,800);

c->Divide(1,3,0,0);

c->cd(1);

h1->SetLabelOffset(1.0,"x");

c_1->SetBottomMargin(0.04);

h1->Draw();

c->cd(2);

h2->SetLabelOffset(1.0,"x");

c_2->SetTopMargin(0.0);

c_2->SetBottomMargin(0.04);

h2->Draw();

c->cd(3);

h3->SetLabelOffset(0.005,"x");

c_3->SetTopMargin(0.0);

h3->Draw();

}

Subject: [ROOT] Drawing histograms close together

Dear Rooters,

I am trying to draw three histograms very close together in the vertical direction. In my script, I use:

c1->Divide(1,3);

c1->cd(1);
h1->SetLabelOffset(1.0,"x");
c1_1->SetBottomMargin(0.001);
h1->Draw();

c1->cd(2);
h2->SetLabelOffset(1.0,"x");
c1_2->SetTopMargin(0.0);
c1_2->SetBottomMargin(0.0);
h2->Draw();

c1->cd(3);
h3->SetLabelOffset(0.005,"x");
c1_3->SetTopMargin(0.0);
h3->Draw();

But the result is not very nice, the x axis of pad 1 (and 2) is sort of cut off, so only the ticks are visible. Also, the histograms are not placed near eachother, but still have some white space between them.
How can I draw them nicely together?

Thanks in advance,

Cecilie
