Bool_t HasTestStatisticData(void) const
HypoTestPlot()
Constructor.
Definition: HypoTestPlot.h:40
This class displays a legend box (TPaveText) containing several legend entries.
Definition: TLegend.h:27
void SetLineColor(Color_t color, const SamplingDistribution *samplDist=0)
Sets line color for given sampling distribution and fill color for the associated shaded TH1F...
const char Option_t
Definition: RtypesCore.h:62
void ApplyResult(HypoTestResult &result, Option_t *opt="NORMALIZE HIST")
Applies a HypoTestResult.
Definition: Rtypes.h:61
HypoTestResult is a base class for results from hypothesis tests.
Double_t AddSamplingDistribution(const SamplingDistribution *samplingDist, Option_t *drawOptions="NORMALIZE HIST")

void SetLineWidth(Width_t lwidth, const SamplingDistribution *samplDist=0)
void ApplyDefaultStyle(void)
Set default style options (also called in the constructor that takes a HypoTestResult).
Double_t AddSamplingDistributionShaded(const SamplingDistribution *samplingDist, Double_t minShaded, Double_t maxShaded, Option_t *drawOptions="NORMALIZE HIST")
Like AddSamplingDistribution, but also sets a shaded area in the minShaded and maxShaded boundaries...
HypoTestResult * fHypoTestResult
