clamp property

bool get clamp

Whether or not the scale currently clamps values to within the range.

If clamping is disabled and the scale is passed a value outside the domain, the scale may return a value outside the range through extrapolation. If clamping is enabled, the return value of the scale is always within the scale’s range. Clamping similarly applies to ScaleContinuousNumberExtension.invert. For example:

var x = ScaleLinear(
  domain: [10, 130],
  range: [0, 960],
  interpolate: interpolateNumber,
);

x(-10); // -160, outside range
x.invert(-160); // -10, outside domain

x.clamp = true;
x(-10); // 0, clamped to range
x.invert(-160); // 10, clamped to domain

Implementation

bool get clamp => _clamp;

set clamp (bool clamp)

Implementation

set clamp(bool clamp) {
  _clamp = clamp;
  _clampf = identity;
  _rescale();
}
