EasingCurve

EasingCurve is a React component that renders a cubic bezier easing curve or easing function as an SVG path. It supports axis lines and customisable styling.

Usage

Import

Once installed, import EasingCurve from "motion-studio".

import { EasingCurve } from "motion-studio"

Draw curve

Given a curve definition, EasingCurve renders a <path /> (and if axisWidth is defined, a <polyline /> component), that you can render as part of an SVG.

function Component() {
    return (
        <svg viewBox="0 0 100 100">
            <EasingCurve
                curve={[0.17, 0.67, 0.83, 0.67]}
                width={100}
                height={100}
            />
        </svg>
    )
}

Props

curve

Required. Either an array of valid bezier curve points:

<EasingCurve curve={[0.17, 0.67, 0.83, 0.67]} />

Or as an easing function:

import { circIn } from "motion"

<EasingCurve curve={circIn} />

Layout

EasingCurve supports width, height, top and left props, defined as pixels, for sizing and positioning the curve.

<EasingCurve
  curve={curve}
  width={100}
  height={100}
  top={20}
/>

Line styling

The drawn curve line can be styled using the color and pathWidth props.

<EasingCurve curve={curve} color="#fff" pathWidth={2} />

Axis styling

The axis lines aren't drawn by default. By setting axisWidth and axisColor these lines will be drawn with the provided values.

<EasingCurve curve={curve} axisWidth={3} axisColor="#333" />

Transition

To enable transitions between different easing curves, provide a transition prop.

<EasingCurve curve={curve} transition={{ duration: 0.3 }} />

This is useful for animating between preset curves, but can feel unresponsive if directly editing a curve.
