Detailed Description

An VariAxis represents a binned histogram axis.

A 1D Histogram would have one VariAxis representing the X axis, while a 2D Histogram would have two axes representing the X and Y VariAxis.

bool LWH::VariAxis::isFixedBinning

(

)

const [inline]

Check if the IAxis has fixed binning, i.e.

if all the bins have the same width.

Returns:

true if the binning is fixed, false otherwise.

Definition at line 59 of file VariAxis.h.

double LWH::VariAxis::lowerEdge

(

)

const [inline]

Get the lower edge of the IAxis.

Returns:

The IAxis's lower edge.

Definition at line 66 of file VariAxis.h.

double LWH::VariAxis::upperEdge

(

)

const [inline]

Get the upper edge of the IAxis.

Returns:

The IAxis's upper edge.

Definition at line 76 of file VariAxis.h.

int LWH::VariAxis::bins

(

)

const [inline]

The number of bins (excluding underflow and overflow) on the IAxis.

Returns:

The IAxis's number of bins.

std::pair<double,double> LWH::VariAxis::binEdges

(

int

index

)

const [inline]

Get the lower edge of the specified bin.

Parameters:

index

The bin number: 0 to bins()-1 for the in-range bins or OVERFLOW or UNDERFLOW.

Returns:

The lower edge of the corresponding bin; for the underflow bin this is Double.NEGATIVE_INFINITY.

(

int

index

)

const [inline]

Get the lower edge of the specified bin.

Parameters:

index

The bin number: 0 to bins()-1 for the in-range bins or OVERFLOW or UNDERFLOW.

Returns:

The lower edge of the corresponding bin; for the underflow bin this is Double.NEGATIVE_INFINITY.

double LWH::VariAxis::binUpperEdge

(

int

index

)

const [inline]

Get the upper edge of the specified bin.

Parameters:

index

The bin number: 0 to bins()-1 for the in-range bins or OVERFLOW or UNDERFLOW.

Returns:

The upper edge of the corresponding bin; for the overflow bin this is Double.POSITIVE_INFINITY.

double LWH::VariAxis::binWidth

(

int

index

)

const [inline]

Get the width of the specified bin.

Parameters:

index

The bin number: 0 to bins()-1) for the in-range bins or OVERFLOW or UNDERFLOW.

Returns:

The width of the corresponding bin.

int LWH::VariAxis::coordToIndex

(

double

coord

)

const [inline]

Convert a coordinate on the axis to a bin number.

If the coordinate is less than the lowerEdge UNDERFLOW is returned; if the coordinate is greater or equal to the upperEdge OVERFLOW is returned.

Parameters:

coord

The coordinate to be converted.

Returns:

The corresponding bin number.

No checking is performed to ensure the argument is a valid bin.
