void ApplyDefaultStyle(void)
Set default style options (also called in the constructor that takes a HypoTestResult).
void ApplyResult(HypoTestResult &result, Option_t *opt="NORMALIZE HIST")
Applies a HypoTestResult.
HypoTestPlot()
Constructor.

HypoTestResult * fHypoTestResult
Definition: HypoTestPlot.h:36
HypoTestResult is a base class for results from hypothesis tests.
SamplingDistribution * GetNullDistribution(void) const
SamplingDistribution * GetAltDistribution(void) const
This class provides simple and straightforward utilities to plot SamplingDistribution objects.
void GetAbsoluteInterval(double &theMin, double &theMax, double &theYMax) const
void SetLineWidth(Width_t lwidth, const SamplingDistribution *samplDist=nullptr)
double AddSamplingDistributionShaded(const SamplingDistribution *samplingDist, double minShaded, double maxShaded, Option_t *drawOptions="NORMALIZE HIST")
Like AddSamplingDistribution, but also sets a shaded area in the minShaded and maxShaded boundaries.
void AddLine(double x1, double y1, double x2, double y2, const char *title=nullptr)
add a line
void SetLineColor(Color_t color, const SamplingDistribution *samplDist=nullptr)
Sets line color for given sampling distribution and fill color for the associated shaded TH1F.
double AddSamplingDistribution(const SamplingDistribution *samplingDist, Option_t *drawOptions="NORMALIZE HIST")
adds the sampling distribution and returns the scale factor
This class simply holds a sampling distribution of some test statistic.
This class displays a legend box (TPaveText) containing several legend entries.
