The API below described how to use the logarithmic-interpolator features.

Options

By default, react-ranger uses linear interpolation between data points, but allows you to easily customize it to use your own interpolation functions by passing an object that implements the following interface.

interpolator

interpolator: {
    getPercentageForValue: (val: number, min: number, max: number): number;
    getValueForClientX: (clientX: number, trackDims: object, min: number, max: number): number;
}

The Interpolator to use. Defaults to the bundled linear-scale interpolator

• getPercentageForValue - Takes the value & range and returns a percentage [0, 100] where the value sits from left to right.
• getValueForClientX- Takes the clientX (offset from the left edge of the ranger) along with the dimensions and range settings and transforms a pixel coordinate back into a value.
