Vue-ChartJs

Is a vue.js wrapper for chart.js. You can easily create your chart components.

Demo

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

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.

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

Just create your own component.

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

export default Bar.extend({
  mounted () {
    // Overwriting base render method with actual data.
    this.renderChart({
      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

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

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

export default Line.extend({
  props: ["data", "options"],
  mounted () {
    this.renderChart(this.data, this.options)
  }
})

Use it in your vue app

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

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

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

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.

// 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:

// 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],
  props: ["chartData", "options"],
  mounted () {
    this.renderChart(this.chartData, this.options)
  }
})

// Load speperate modules with destructure assign
import { Line, mixins } from 'vue-chartjs'
const { reactiveProp } = mixins

export default Line.extend({
  mixins: [reactiveProp],
  props: ["chartData", "options"],
  mounted () {
    this.renderChart(this.chartData, this.options)
  }
})
