# `avar`: Axis Variations Table

  Axis Variations Table

  This class represents the `avar` table of a variable font. The object has one substantive attribute, `segments`, which maps axis tags to a segments dictionary:

      >>> font["avar"].segments
      {'wght': {-1.0: -1.0,
        0.0: 0.0,
        0.125: 0.11444091796875,
        0.25: 0.23492431640625,
        0.5: 0.35540771484375,
        0.625: 0.5,
        0.75: 0.6566162109375,
        0.875: 0.81927490234375,
        1.0: 1.0},
       'ital': {-1.0: -1.0, 0.0: 0.0, 1.0: 1.0}}

  Notice that the segments dictionary is made up of normalized values. A valid `avar` segment mapping must contain the entries `-1.0: -1.0, 0.0: 0.0, 1.0: 1.0`. fontTools does not enforce this, so it is your responsibility to ensure that mappings are valid.
