-> VueJS wrapper for ChartJs
+Is a vue.js wrapper for chart.js. You can easily create your chart components.
+
+## Demo
+
+[Demo](https://apertureless.github.io/vue-chartjs/)
+
+### Compatibility
+
+- v1 later
+  - Vue.js 1.x
+- v2 later
+  - Vue.js 2.x
+
+After the final release of vue.js 2, you also get the v2 per default if you install vue-chartjs over npm.
+No need for the @next tag anymore. If you want the v1 you need to define the version.
+If you're looking for v1 check this [branch](https://github.com/apertureless/vue-chartjs/tree/release/1.1.3)

+## Reactivity
+
+Chart.js does not update or re-render the chart if new data is passed.
+However you can simply implement this by your own or use one of the two mixins which are included.
+
+- `reactiveProp`
+- `reactiveData`
+
+Both are included in the `mixins` module.
+
+The mixins automatically create `chartData` as a prop or data. And add a watcher. If data has changed, the chart will update.
+
+```javascript
+// MonthlyIncome.js
+import { Line, mixins } from 'vue-chartjs'
+
+export default Line.extend({
+  mixins: [mixins.reactiveProp],
+  props: ["chartData", "options"],
+  mounted () {
+    this.renderChart(this.chartData, this.options)
+  }
+})
+
+```
+
+### Mixins module
+The `mixins` module is included in the `VueCharts` module and as a seperate module.
+Some ways to import them:
+
+```javascript
+// Load complete module with all charts
+import VueCharts from 'vue-chartjs'
+
+export default VueCharts.Line.extend({
+  mixins: [VueCharts.mixins.reactiveProp],
+  props: ["chartData", "options"],
+  mounted () {
+    this.renderChart(this.chartData, this.options)
+  }
+})
+```

+// Load speperate modules
+import { Line, mixins } from 'vue-chartjs'

+export default Line.extend({
+  mixins: [mixins.reactiveProp],

+})
