Supports Chart.js, Google Charts, and Highcharts

Quick Start

Run

npm install vue-chartkick chart.js

The latest version works with Vue 3. For Vue 2, use version 0.6.1 and this readme.

And add it to your app

import VueChartkick from 'vue-chartkick'
import 'chartkick/chart.js'

app.use(VueChartkick)

This sets up Chartkick with Chart.js. For other charting libraries, see detailed instructions.

Multiple series

data = [
  {name: 'Workout', data: {'2021-01-01': 3, '2021-01-02': 4}},
  {name: 'Call parents', data: {'2021-01-01': 5, '2021-01-02': 3}}
];

and

<line-chart :data="data"></line-chart>

Data

Data can be an array, object, callback, or URL.

Array

<line-chart :data="[['2021-01-01', 2], ['2021-01-02', 3]]"></line-chart>

Object

<line-chart :data="{'2021-01-01': 2, '2021-01-02': 3}"></line-chart>

Callback

function fetchData(success, fail) {
  success({"2021-01-01": 2, "2021-01-02": 3})
  // or fail("Data not available")
}

and

<line-chart :data="fetchData"></line-chart>

URL

Make your pages load super fast and stop worrying about timeouts. Give each chart its own endpoint.

<line-chart data="/stocks"></line-chart>

Options

Id, width, and height

<line-chart id="users-chart" width="800px" height="500px"></line-chart>

Min and max values

<line-chart :min="1000" :max="5000"></line-chart>

min defaults to 0 for charts with non-negative values. Use null to let the charting library decide.

Min and max for x-axis - Chart.js

<line-chart xmin="2021-01-01" xmax="2022-01-01"></line-chart>

Colors

<line-chart :colors="['#b00', '#666']"></line-chart>

Stacked columns or bars

<column-chart :stacked="true"></column-chart>

Discrete axis

<line-chart :discrete="true"></line-chart>

Label (for single series)

<line-chart label="Value"></line-chart>

Axis titles

<line-chart xtitle="Time" ytitle="Population"></line-chart>

Straight lines between points instead of a curve

<line-chart :curve="false"></line-chart>

Show or hide legend

<line-chart :legend="true"></line-chart>

Specify legend position

<line-chart legend="bottom"></line-chart>

Donut chart

<pie-chart :donut="true"></pie-chart>

Prefix, useful for currency - Chart.js, Highcharts

<line-chart prefix="$"></line-chart>

Suffix, useful for percentages - Chart.js, Highcharts

<line-chart suffix="%"></line-chart>

Set a thousands separator - Chart.js, Highcharts

<line-chart thousands=","></line-chart>

Set a decimal separator - Chart.js, Highcharts

<line-chart decimal=","></line-chart>

Set significant digits - Chart.js, Highcharts

<line-chart :precision="3"></line-chart>

Set rounding - Chart.js, Highcharts

<line-chart :round="2"></line-chart>

Show insignificant zeros, useful for currency - Chart.js, Highcharts

<line-chart :round="2" :zeros="true"></line-chart>

Friendly byte sizes - Chart.js 2.8+

<line-chart :bytes="true"></line-chart>

Specify the message when the chart is loading

<line-chart loading="Loading..."></line-chart>

Specify the message when data is empty

<line-chart empty="No data"></line-chart>

Refresh data from a remote source every n seconds

<line-chart :refresh="60"></line-chart>

You can pass options directly to the charting library with:

<line-chart :library="{backgroundColor: '#eee'}"></line-chart>

See the documentation for Google Charts, Highcharts, and Chart.js for more info.

To customize datasets in Chart.js, use:

<line-chart :dataset="{borderWidth: 10}"></line-chart>

You can pass this option to individual series as well.

Use dynamic components to make the chart type dynamic:

<component is="column-chart"></component>

Reactivity

While some of the examples use object or array literals in props for demonstration, this can lead to unnecessary re-renders.

<line-chart :library="{backgroundColor: '#eee'}"></line-chart>

Instead, use a data property:

<line-chart :library="library"></line-chart>

See this discussion for more details.

Global Options

To set options for all of your charts, use:

Chartkick.options = {
  colors: ["#b00", "#666"]
}

Multiple Series

You can pass a few options with a series:

• name
• data
• color
• dataset - Chart.js only
• points - Chart.js only
• curve - Chart.js only

Download Charts

Chart.js only

Give users the ability to download charts. It all happens in the browser - no server-side code needed.

<line-chart :download="true"></line-chart>

Set the filename

<line-chart download="boom"></line-chart>

Note: Safari will open the image in a new window instead of downloading.

Set the background color

<line-chart :download="{background: '#fff'}"></line-chart>
