linear()は、continuous Scaleをlinearish()でlinear化して返す。要はlinear Scaleを返す.
export default function continuous(deinterpolate, reinterpolate) {
......
function rescale() {
piecewise = Math.min(domain.length, range.length) > 2 ? polymap : bimap;
output = input = null;
return scale;
}
function scale(x) {
return (output || (output = piecewise(domain, range, clamp ? deinterpolateClamp(deinterpolate) : deinterpolate, interpolate)))(+x);
}
......
scale.domain = function(_) {
return arguments.length ? (domain = map.call(_, number), rescale()) : domain.slice();
};
......
return rescale();
}
continuousはscale関数を返す. だからscale(x)でスケーリングできるんだね
