Method Detail
-
binCentre
public double binCentre(int index)
Description copied from interface:IAxis
Centre of the bin specified.
-
binLowerEdge
public double binLowerEdge(int index)
Description copied from interface:IAxis
Lower edge of the specified bin.- Specified by:
binLowerEdge
in interfaceIAxis
- 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.
-
binUpperEdge
public double binUpperEdge(int index)
Description copied from interface:IAxis
Upper edge of the specified bin.- Specified by:
binUpperEdge
in interfaceIAxis
- 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.
-
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 interfaceIAxis
-
lowerEdge
public double lowerEdge()
Description copied from interface:IAxis
Lower axis edge.
-
upperEdge
public double upperEdge()
Description copied from interface:IAxis
Upper axis edge.
-
xgetBin
int xgetBin(double coord)
This package private method is similar to coordToIndex except that it returns our internal definition for overflow/underflow
-
xmap
int xmap(int index)
Package private method to map from the external representation of bin number to our internal representation of bin number
