    - #### ChromaticitySpectrum

          public ChromaticitySpectrum​(float x,
                                      float y)

  - ### Method Detail

    - #### sample

          public float sample​(float lambda)

      Description copied from class: `SpectralCurve`
      This function determines the actual spectral curve data. Note that the lambda parameter is assumed to be in nanometers.
      Specified by:
        `sample` in class `SpectralCurve`
      Parameters:
        `lambda` - wavelength to sample in nanometers
      Returns:
        the value of the spectral curve at this point

    - #### get

          public static final XYZColor get​(float x,
                                           float y)
