Constructor Detail

FixedAxis

public FixedAxis(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: IAxis
Centre of the bin specified.

Specified by:
binCentre in interface IAxis
Parameters:
index - Bin number (0...bins()-1) or OVERFLOW or UNDERFLOW.

binLowerEdge

public double binLowerEdge(int index)
Description copied from interface: IAxis
Lower edge of the specified bin.

Specified by:
binLowerEdge in interface IAxis
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: IAxis
The number of bins (excluding underflow and overflow) on the axis.

Specified by:
bins in interface IAxis

binUpperEdge

public double binUpperEdge(int index)
Description copied from interface: IAxis
Upper edge of the specified bin.

Specified by:
binUpperEdge in interface IAxis
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: IAxis
Width of the bin specified.

Specified by:
binWidth in interface IAxis
Parameters:
index - Bin number (0...bins()-1) or OVERFLOW or UNDERFLOW.

coordToIndex

public int coordToIndex(double coord)
Description copied from interface: IAxis
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 IAxis

lowerEdge

public double lowerEdge()
Description copied from interface: IAxis
Lower axis edge.

Specified by:
lowerEdge in interface IAxis

upperEdge

public double upperEdge()
Description copied from interface: IAxis
Upper axis edge.

Specified by:
upperEdge in interface IAxis
