Setting X range with t-efficienct

Newbie

currently i have a Tefficiency from (0,8256), but I need to divide in three planes, how can i set my x range?

Hi,

In order to better understand what you’re trying to achieve, can you give us a small ROOT macro of what you’re doing and the ROOT version you use?

Thanks,
Jakob

    TH1D *totalEvents = new TH1D("h_total","tot", 8256,0,8256);
    TH1D *passEvents = new TH1D("h_pass", "pass", 8256,0,8256);
    TH1D *htotal = new TH1D("samples_total","s_tot",8256,0,8256);
    TH1D *ptotal = new TH1D("samples_pass","p_sam",8256,0,8256);
    for (int j = 0; j < 8256; j++ )
    {
        if (ROIs[j] != 0)
        {
            flippedROIs->Fill(j,flipROI[j]/ROIs[j]);
        }
        if (samples[j] != 0)
        {
            flippedSamples->Fill(j,totalflips[j]/samples[j]);
        }
        totalEvents->SetBinContent(j,ROIs[j]);
        passEvents->SetBinContent(j,flipROI[j]);
        htotal->SetBinContent(j,samples[j]);
        ptotal->SetBinContent(j,totalflips[j]);

    if (TEfficiency::CheckConsistency(*passEvents,*totalEvents))
    {
        pEff = new TEfficiency(*passEvents,*totalEvents);
        TEfficiency* pCopy = new TEfficiency(*pEff);
        //pCopy->SetConfidenceLevel(.90);
        pCopy->SetStatisticOption(TEfficiency::kFCP);
        pCopy->SetTitle("Probability of Flipped Bit Per ROI for Run 17990 1000 events; Wires; ROIs with Flipped bit over Total ROIs");
        f_output.cd();
        pEff->Write();
        pCopy->Write();
        c1.cd();
        pCopy->Draw("AP");
        c1.Print(".png");
        
    }

I want to divide pCopy in three different ranges rather than have all 8256 points in one plot

I guess @moneta can help
