[Rivet] ratio plot

[Sercan Sen]

Hi,

There is a plot at the attachment.

I would like to get the ratios "r1 = a / b" and
"r2 = c / d" and plot r1, r2 on the RATIO plot.

Is there an option for this in make-plots script ?

It's easy to do it in ROOT but for some reasons
I would like to do it in Rivet.

// in ROOT: .. first, plot a and b in a canvas... and create a TPad  
for the ratio plot..
    TPad *pad = new TPad("pad","pad",0,0,1,0.3);
    pad->SetTopMargin(0);
    pad->Draw();
    pad->cd();
    a->Sumw2();
    a->SetStats(0);
    a->Divide(b);
    a->Draw("ep");
    ...

Cheers
Sercan
