## README

# qchart

创建 Chart 的方式如下：

```javascript
new qchart.Chart()
```

创建一个 chart 实例，返回一个 Chart 对象。

`new qchart.Chart()` 的流程如图。

## 图表结构与交互

## 绘制图表

绘制指定类型的图表的使用方法为：`chart.<visualType>()`。如绘制饼图：

```javascript
chart
  .pie({
    radius: 0.6,
    innerRadius: 0.2
  })
  .source() /* 数据 */
  .setDataFields(/* 数据处理方式 */)
```

在 `qchart` 中将传统的图表类型（如：`pie` 和 `line`）区分为 `visual`，意为一种可视类型。可以在一个 `chart` 上连续多次调用 `chart.<visualType>()`。

可以使用 `qchart.Chart.supportedVisuals()` 查看已支持的可视类型。

## plugin 插件

当需要使用额外的辅助组件时，`Chart` 提供了相应的插件机制应用辅助组件，方法签名为：`addPlugin(plugin)`。

```javascript
chart.addPlugin(/* some plugin */)
```
