Method Summary

All Methods Instance Methods Concrete Methods
Modifier and Type	Method and Description
`double`	`calibratedValue(double rawValue)` Returns a calibrated value given a raw position along the axis.
`double`	`coeff(int i)` Gets the `i`th coefficient of the polynomial.
`PolynomialAxis`	`copy()` Creates an exact duplicate of this axis.
`int`	`degree()` Gets the degree of the polynomial (i.e., the largest exponent with a non-zero coefficient).
`String`	`generalEquation()` Gets the general equation representing values along this axis; for instance: `y = m*x + b`.
`double`	`rawValue(double calibratedValue)` Returns a raw value given a calibrated position along the axis.
`void`	`setCoeff(int i, double v)` Sets the `i`th coefficient of the polynomial.

- Method Detail
  - degree
```
public int degree()
```
    Gets the degree of the polynomial (i.e., the largest exponent with a non-zero coefficient).
  - coeff
```
public double coeff(int i)
```
    Gets the ith coefficient of the polynomial.
  - setCoeff
```
public void setCoeff(int i,
                     double v)
```
    Sets the ith coefficient of the polynomial.
  - calibratedValue
```
public double calibratedValue(double rawValue)
```
    Description copied from interface: CalibratedAxis
    
    Returns a calibrated value given a raw position along the axis.
  - rawValue
```
public double rawValue(double calibratedValue)
```
    Description copied from interface: CalibratedAxis
    
    Returns a raw value given a calibrated position along the axis. Returns Double.NaN if the calibrated value maps to more than one point along axis.
  - generalEquation
```
public String generalEquation()
```
    Description copied from interface: CalibratedAxis
    
    Gets the general equation representing values along this axis; for instance: y = m*x + b.
