domain property

@override List<num> get domain

The scale's domain that specifies the input values.

Implementation

@override
get domain => [_x0, _x1, _x2];

@override set domain (List<num> domain)

Implementation

@override
set domain(domain) {
  _x0 = domain[0];
  _x1 = domain[1];
  _x2 = domain[2];
  _t0 = _transform(_x0);
  _t1 = _transform(_x1);
  _t2 = _transform(_x2);
  _k10 = _t0 == _t1 ? 0 : 0.5 / (_t1 - _t0);
  _k21 = _t1 == _t2 ? 0 : 0.5 / (_t2 - _t1);
  _s = _t1 < _t0 ? -1 : 1;
}
