## Props

| Prop         | type          | Description                                                                                 | Required |
| ------------ | ------------- | ------------------------------------------------------------------------------------------- | -------- |
| `initScript` | string        | 初始化图表的 js 代码，参考 f2 的文档                                                        | `yes`    |
| `data`       | Array<Object> | f2 chart source                                                                             | `no`     |
| `onChange`   | Function      | tooltip onchange                                                                            | `no`     |
| `webView`    | ReactElement  | 渲染图表的 webview，可以使用 react-native-webview 代替，默认使用 react-natve 里面的 webview | `no`     |

## Notice

- canvas的id 是 'chart'，不是文档中的 'mountNode'
- chart 已经在源码的 html 定义过了，在 `initScript` 中，并不需要定义 chart，直接给 chart 赋值即可
- tooltip onchange 中 传输数据时用到的 `stringify` 也是在 html 定义好的，可以直接使用，用 `JSON.stringify` 会报错, [原因](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Errors/Cyclic_object_value)
- 如果使用的是 `react-native-webview`，在 tooltip 中的 `postMessage` 应该为 `window.ReactNativeWebView.postMessage`
