> VueJS wrapper for ChartJs

## Install

Simply run `npm install vue-chartjs`

## How to use

You need to import the base chart class and extend it. This gives much more flexibility when working with different data. You can pass the data over props or vue-resource.

You can import the whole package or each module individual.

```javascript
import VueCharts from 'vue-chartjs'
import { Bar, Line } from 'vue-chartjs'
```

Just create your own component.

```javascript
// CommitChart.js
import { Bar } from 'vue-chartjs'

export default BarChart.extend({
  ready () {
    // Overwriting base render method with actual data.
    this.render({
      labels: ['January', 'February', 'March', 'April', 'May', 'June', 'July', 'August', 'September', 'October', 'November', 'December'],
      datasets: [
        {
          label: 'GitHub Commits',
          backgroundColor: '#f87979',
          data: [40, 20, 12, 39, 10, 40, 39, 80, 40, 20, 12, 11]
        }
      ]
    })
  }
})
```

Then simply import and use your own extended component and use it like a normal vue component

```javascript
import CommitChart from 'path/to/component/CommitChart'
```

## Another Example with options

You can overwrite the default chart options. Just pass the options object as a second paramenter to the render method

```javascript
// MonthlyIncome.js
import { Line } from 'vue-chartjs'

export default LineChart.extend({
  props: [data, options],
  ready () {
    this.render(this.data, this.options)
  }
})
```

Use it in your vue app

```javascript
import MonthlyIncome from 'path/to/component/MonthlyIncome'

<template>
  <monthly-income :data={....} />
</template>

<script>
export default {
  components: { MonthlyIncome },
  ....
}
</script>
```
