Constructor Detail

DoubleFixedAxis

public DoubleFixedAxis(int bins,
                       double min,
                       double max)

Create an Axis

Parameters:

bins - Number of bins

min - Minimum for axis

max - Maximum for axis

Method Detail

binCentre

public double binCentre(int index)

Description copied from interface: DoubleIAxis

Centre of the bin specified.

Specified by:

binCentre in interface DoubleIAxis

Parameters:

index - Bin number (0...bins()-1) or OVERFLOW or UNDERFLOW.

binLowerEdge

public double binLowerEdge(int index)

Description copied from interface: DoubleIAxis

Lower edge of the specified bin.

Specified by:

binLowerEdge in interface DoubleIAxis

Parameters:

index - Bin number (0...bins()-1) or OVERFLOW or UNDERFLOW.

Returns:

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

bins

public int bins()

Description copied from interface: DoubleIAxis

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

Specified by:

bins in interface DoubleIAxis

binUpperEdge

public double binUpperEdge(int index)

Description copied from interface: DoubleIAxis

Upper edge of the specified bin.

Specified by:

binUpperEdge in interface DoubleIAxis

Parameters:

index - Bin number (0...bins()-1) or OVERFLOW or UNDERFLOW.

Returns:

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

binWidth

public double binWidth(int index)

Description copied from interface: DoubleIAxis

Width of the bin specified.

Specified by:

binWidth in interface DoubleIAxis

Parameters:

index - Bin number (0...bins()-1) or OVERFLOW or UNDERFLOW.

coordToIndex

public int coordToIndex(double coord)

Description copied from interface: DoubleIAxis

Converts a coordinate on the axis to a bin number. If the coordinate is < lowerEdge returns UNDERFLOW, and if the coordinate is >= upperEdge returns OVERFLOW.

Specified by:

coordToIndex in interface DoubleIAxis

lowerEdge

public double lowerEdge()

Description copied from interface: DoubleIAxis

Lower axis edge.

Specified by:

lowerEdge in interface DoubleIAxis

upperEdge

public double upperEdge()

Description copied from interface: DoubleIAxis

Upper axis edge.

Specified by:

upperEdge in interface DoubleIAxis
