Package Exports

d3-interpolate-curve

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (d3-interpolate-curve) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

d3-interpolate-curve

This module provides a select of methods for generating number value interpolators from D3 curve functions.

Installing

If you use NPM, npm install d3-interpolate-curve. Otherwise, download the latest release. Alternativly in vanilla JS:

<script src="https://raw.githack.com/jamesleesaunders/d3-interpolate-curve/dist/d3-interpolate.js"></script>
<script>

var interpolate = d3.interpolateFromCurve([1,2,7,2], d3.curveMonotoneX, 0.00001, 100);

</script>

API Reference

# d3.interpolateFromCurve(values, curve, epsilon, samples) · Source, Examples

Returns interpolator based on D3 curve function; d3.curveCardinal(), d3.curveLinear(), d3.curveMonotoneX() etc.

var interpolate = d3.interpolateFromCurve([1,2,7,2], d3.curveMonotoneX, 0.00001, 100);

# d3.interpolateCardinal(values) · Source, Examples

Returns interpolator based on cubic Cardinal spline.

var interpolate = d3.interpolateCardinal([1,2,7,2]);

# d3.interpolateCatmullRom(values) · Source, Examples

Returns interpolator based on a cubic Catmull–Rom spline.

var interpolate = d3.interpolateCatmullRom([1,2,7,2]);

# d3.interpolateMonotoneX(values) · Source, Examples

Returns interpolator based on MonotoneX spline.

var interpolate = d3.interpolateMonotoneX([1,2,7,2]);
