Package Exports

@antv/scale
@antv/scale/esm
@antv/scale/esm/index.js
@antv/scale/lib
@antv/scale/lib/index.js

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 (@antv/scale) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

🔨 上手

基本用法

import { Linear, LinearOptions } from '@antv/scale';

const options: LinearOptions = {
  domain: [0, 10],
  range: [0, 100],
};
const x = new Linear(options);

x.map(2); // 20
x.invert(20); // 2
x.getTicks(); // [0, 2.5, 5, 7.5, 10]

自定义可读 tickMethod

import { Linear } from '@antv/scale';

const x = new Linear({
  domain: [0, 10],
  range: [0, 100],
  tickCount: 3,
  tickMethod: () => [0, 5, 10],
});

x.getTicks(); // [0, 5, 10]
