vue-chartjs is a wrapper for Chart.js in Vue. It allows you to create various types of charts using the Chart.js library while leveraging the reactive data-binding and component-based architecture of Vue.js.

What are vue-chartjs's main functionalities?

Line Chart

This code sample demonstrates how to create a simple line chart using vue-chartjs. The `Line` component from vue-chartjs is used to render the chart, and the data and options are passed as props.

```javascript
<template>
  <line-chart :chart-data="datacollection" :options="options"></line-chart>
</template>

<script>
import { Line } from 'vue-chartjs'

export default {
  components: {
    LineChart: Line
  },
  data () {
    return {
      datacollection: {
        labels: ['January', 'February', 'March', 'April', 'May', 'June', 'July'],
        datasets: [
          {
            label: 'Data One',
            backgroundColor: '#f87979',
            data: [40, 39, 10, 40, 39, 80, 40]
          }
        ]
      },
      options: {
        responsive: true,
        maintainAspectRatio: false
      }
    }
  }
}
</script>
```

Bar Chart

This code sample demonstrates how to create a bar chart using vue-chartjs. The `Bar` component is used to render the chart, and the data and options are passed as props.

```javascript
<template>
  <bar-chart :chart-data="datacollection" :options="options"></bar-chart>
</template>

<script>
import { Bar } from 'vue-chartjs'

export default {
  components: {
    BarChart: Bar
  },
  data () {
    return {
      datacollection: {
        labels: ['January', 'February', 'March', 'April', 'May', 'June', 'July'],
        datasets: [
          {
            label: 'Data One',
            backgroundColor: '#f87979',
            data: [40, 39, 10, 40, 39, 80, 40]
          }
        ]
      },
      options: {
        responsive: true,
        maintainAspectRatio: false
      }
    }
  }
}
</script>
```

Pie Chart

This code sample demonstrates how to create a pie chart using vue-chartjs. The `Pie` component is used to render the chart, and the data and options are passed as props.

```javascript
<template>
  <pie-chart :chart-data="datacollection" :options="options"></pie-chart>
</template>

<script>
import { Pie } from 'vue-chartjs'

export default {
  components: {
    PieChart: Pie
  },
  data () {
    return {
      datacollection: {
        labels: ['Red', 'Blue', 'Yellow', 'Green', 'Purple', 'Orange'],
        datasets: [
          {
            label: 'Data One',
            backgroundColor: ['#FF6384', '#36A2EB', '#FFCE56', '#4BC0C0', '#9966FF', '#FF9F40'],
            data: [12, 19, 3, 5, 2, 3]
          }
        ]
      },
      options: {
        responsive: true,
        maintainAspectRatio: false
      }
    }
  }

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 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

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 LineChart.extend({
  props: [data, options],
  ready () {
    this.render(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>
