Method Detail

binCentre

double binCentre(int index)
Centre of the bin specified.

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

binLowerEdge

double binLowerEdge(int index)
Lower edge of the specified bin.

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

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


binUpperEdge

double binUpperEdge(int index)
Upper edge of the specified bin.

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

double binWidth(int index)
Width of the bin specified.

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

coordToIndex

int coordToIndex(double coord)
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.


lowerEdge

double lowerEdge()
Lower axis edge.


upperEdge

double upperEdge()
Upper axis edge.
