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
