void pad2() {

    TH1F *h = new TH1F("h","test",100,-3,3);     h->FillRandom("gaus",1000);
    TCanvas *c1 = new TCanvas("c1");
    c1->Divide(2,1);
    c1->cd(1);
    h->DrawCopy();
    c1->cd(2);
    h->FillRandom("gaus",5000);
    h->Draw();
    c1->cd();
    TPad *trans = new TPad("trans","",0,0,1,1);

    trans->SetFillStyle(4000);
    trans->Draw();
    trans->cd();

    TLine *line = new TLine(.2,.5,.7,.8);

    line->SetLineColor(kRed);
    line->SetLineWidth(4);
    line->Draw();

}
