Detailed Description

Renders a digitizer's analog/digital/thresholded views as ROOT TH2D histograms (libqupidVis).

Friend of the digitizer classes. Every histogram is heap-allocated and owned by the caller (subject to the usual ROOT directory ownership rules).

Warning

All three histogram builders take both axis ranges from GetSizeY(), and DrawDigitalSignalText takes the y pixel count from GetNPixelX(): the output is laid out correctly only for square matrices.

Member Function Documentation

AnalogSignal()

TH2D * QPGraphFactory::AnalogSignal

(

int

ndiv = 100

)

ndiv×ndiv sampling of GetAnalogSignal over the matrix.

Parameters

ndiv	bins per axis

Returns

caller-owned histogram of the analog signal density

Definition at line 12 of file QPGraphFactory.cpp.

References QPDigitizerBase::GetAnalogSignal(), GetDigitizer(), and QPDigitizerBase::GetSizeY().

DigitalSignal()

TH2D * QPGraphFactory::DigitalSignal

(

)

One bin per pixel, filled with the pixel's integrated digital signal (electrons).

Returns

caller-owned histogram of the digital signal

Definition at line 31 of file QPGraphFactory.cpp.

DigitizedSignal()

TH2D * QPGraphFactory::DigitizedSignal

(

double

threshold = 0.1

)

Binary fired-pixel map: 1 where the digital signal exceeds threshold, 0 elsewhere.

Parameters

threshold

firing threshold, electrons

Returns

caller-owned histogram of the thresholded signal

DrawDigitalSignalText()

void QPGraphFactory::DrawDigitalSignalText

(

TH2D *

h = nullptr

)

Draws each pixel's digital value as a TText on the current pad.

The text objects are left to the pad.

Parameters

h	histogram whose bin centers position the labels; when nullptr the positions are computed from the digitizer geometry

DrawPixelLinse()

void QPGraphFactory::DrawPixelLinse

(

TH2D *

h = nullptr

)

Not implemented; the body is empty.

Parameters

h

unused

Definition at line 107 of file QPGraphFactory.cpp.

GetDigitizer()

QPDigitizerBase * QPGraphFactory::GetDigitizer ( ) const

inline

Returns

the rendered digitizer; not owned
