MPF.significanceScanPlot module¶
Similiar to Plot()
, but also shows a
significance scan for all added signals in the second pad.
For further options see PlotStore()
Example¶
#!/usr/bin/env python
import ROOT
from MPF.significanceScanPlot import SignificanceScanPlot
from MPF.atlasStyle import setAtlasStyle
setAtlasStyle()
bkg1 = ROOT.TH1F("bkg1", "", 20, -2, 4)
bkg2 = ROOT.TH1F("bkg2", "", 20, -2, 4)
data = ROOT.TH1F("data", "", 20, -2, 4)
signal = ROOT.TH1F("signal", "", 20, -2, 4)
signal2 = ROOT.TH1F("signal2", "", 20, -2, 4)
bkg1.FillRandom("gaus")
bkg1.Scale(0.01)
bkg2.FillRandom("gaus")
bkg2.Scale(0.01)
shiftGaus = ROOT.TF1("shiftGaus", "TMath::Gaus(x, 2)")
signal.FillRandom("shiftGaus")
signal.Scale(0.003)
shiftGaus2 = ROOT.TF1("shiftGaus2", "TMath::Gaus(x, 1.5, 0.5)")
signal2.FillRandom("shiftGaus2")
signal2.Scale(0.005)
p = SignificanceScanPlot(xTitle="x")
p.registerHist(bkg1, style="background", process="Bkg 1", color="kGray+1")
p.registerHist(bkg2, style="background", process="Bkg 2", color="kGray+2")
p.registerHist(signal, style="signal", process="Signal 1", color="kRed", lineWidth=3)
p.registerHist(signal2, style="signal", process="Signal 2", color="kPink+1", lineWidth=3)
p.saveAs("plot.pdf")

SignificanceScanPlot
(drawCumulativeStack=False, drawBackgroundContributionHisto=False, significancePadTitle='Z', significanceMode='BinomialExpZ', significanceFunction=None, cumulativeStackTitle='Cumulative', scanDirection='forward', processesOfInterest=None, **kwargs)[source]¶ Bases:
MPF.plotStore.PlotStore
Overwrites the defaults for the following
PlotStore()
parameters:Parameters: - ratioUp – If set, used for the y-Axis maximum on the scan pad default: None
- ratioDown – If set, used for the y-Axis minimum on the scan pad default: None
Plot specific options:
Parameters: - significancePadTitle – y-Axis title for the significance pad
- drawCumulativeStack – draw the stack of cumulative distributions in a 3rd pad
- drawBackgroundContributionHisto – draw the relative background contributions in a 3rd pad
- cumulativeStackTitle – title for the cumulative distribution pad if given
- significanceMode/significanceFunction – see
getSignificanceHistogram()
- scanDirection – [forward, backwards, both]
- processesOfInterest – list of process names to be considered as signal, None defaults to all signal processes

saveAs
(path, **kwargs)[source]¶ Save the canvas. Arguments are passed to
MPF.canvas.Canvas.saveAs()
