## Design Guide

### 元素构成

子弹图的发明是为了取代仪表盘上常见的那种里程表，时速表等基于圆形的信息表达方式。更多可以查看：[Bullet Graph Design Specification](https://www.perceptualedge.com/articles/misc/Bullet_Graph_Design_Spec.pdf)

<img alt="design" src="https://zos.alipayobjects.com/rmsportal/DkOloAVoymGGRJgmezOc.png" width='600'>

## Quick start

<div class='sign'>

```ts
import { Bullet } from '@antv/g2plot';

const data = [
  {
    title: '满意度',
    ranges: [100],
    measures: [80],
    target: 85,
  },
];

const bulletPlot = new Bullet('container', {
  data: [{ title: '满意度', ranges: [100], measures: [80], target: 85 }],
  measureField: 'measures',
  rangeField: 'ranges',
  targetField: 'target',
  xField: 'title',
  color: {
    range: '#f0efff',
  },
  yAxis: false,
});

bulletPlot.render();
```

</div>
