# echarts-plus

[![NPM version][npm-image]][npm-url]

A visualization grammar extension for [Echarts](http://echarts.baidu.com/) to make it more powerful. 

## Why use echarts-plus?

Echarts is awsome, but build echarts series option is annoying. echarts-plus use a visualization grammar to build echarts option. It let you build echarts option from data become quick and more effective.

Echarts 很强大，但是它的配置的设计是从图表本身的角度出发的。所以会导致从数据构建到 echarts 的配置变得很不友好。echarts-plus 从数据可视化本身出发，通过一套可视化语法来让创建echarts图表配置变得更高效。

## Quick Start

Simple demo code:

```html
<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="UTF-8">
  <title>echarts-plus demo</title>
  <link rel="stylesheet" href="highlight.css">
</head>
<body>
  <div id="main" style="width:800px;height:400px;"></div>
  <script src="../dist/echarts-plus-all.js"></script>
  <script>
  new EChartsPlus([{
    dt: '2016-01-01',
    value: 21323
  }, {
    dt: '2016-01-02',
    value: 16528
  }, {
    dt: '2016-01-03',
    value: 16028
  }], {
    coord: 'rect',
    series: [{
      type: 'bar',
      visions: [{
        channel: 'y',
        field: 'value'
      }, {
        channel: 'x',
        field: 'dt'
      }]
    }],
    option: {
      title: {
        text: '直角坐标系demo'
      }
    }
  }).renderTo('main')
  </script>
</body>
</html>
```

Then you will get:

When you need write a echarts-plus option, you only need follow next steps:

1. Choose a coord system, `(map | polar | rect )`.
2. Mapping your data column to vision channel of the coord system.
3. Done! Just try it.

当你需要构造一个ecahrts-plus的配置的时候，你只需要按照如下几部即可

1. 选择一个坐标系，当前有`(map | polar | rect )`坐标系可选。
2. 配置数据列到视觉通道的映射。
3. 完成！谁用谁知道。
