Say Goodbye To Timeouts

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="2018-01-01" xmax="2019-01-01"></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>

Show a message when data is empty

<line-chart :messages="{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>

Global Options

To set options for all of your charts, use:

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

Data

Pass data as an array or object

<pie-chart :data="{'Blueberry': 44, 'Strawberry': 23}"></pie-chart>
<pie-chart :data="[['Blueberry', 44], ['Strawberry', 23]]"></pie-chart>

Times can be a Date or a string (strings are parsed)

<line-chart :data="[[new Date(), 5], ['2017-01-01 00:00:00 UTC', 7]]"></line-chart>

Data can also be a callback

function fetchData(success, fail) {
  success({"Blueberry": 44, "Strawberry": 23})
  // or fail("Data not available")
}

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

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>

Run

yarn add vue-chartkick chart.js
