Methods

toURL() : String

Get the full Image-Charts API url (signed and encoded if necessary)

Usage
import ImageCharts from 'image-charts';

const chart_url = ImageCharts()
.cht('bvg') // vertical bar chart
.chs('300x300') // 300px x 300px
.chd('a:60,40') // 2 data points: 60 and 40
.toURL(); // get the generated URL

console.log(chart_url); // https://image-charts.com/chart?cht=bvg&chs=300x300&chd=a%3A60%2C40

toFile(file) : Promise<()>

Creates a file containing generated chart image and yield a promise.

When file is a filename, asynchronously writes data to the file, replacing the file if it already exists. When file is a file descriptor, the behavior is similar to calling fs.write() directly (which is recommended).

Usage
import ImageCharts from 'image-charts';

const chart_path = '/tmp/chart.png';

ImageCharts()
.cht('bvg') // vertical bar chart
.chs('300x300') // 300px x 300px
.chd('a:60,40') // 2 data points: 60 and 40
.toFile(chart_path)
.then(() => console.log('Image chart written at %s', chart_path))

toBuffer() : Promise<Buffer>

Do a request to Image-Charts API with current configuration and yield a promise of a NodeJS buffer

Usage
import ImageCharts from 'image-charts';

const chart_url = ImageCharts()
.cht('bvg') // vertical bar chart
.chs('300x300') // 300px x 300px
.chd('a:60,40') // 2 data points: 60 and 40
.toBuffer(); // download chart image as a buffer

console.log(chart_url); // <Buffer 89 50 4e 47 0d 0a 1a 0a 00 00 00 ...

toDataURI() : String

Do a request to Image-Charts API with current configuration and yield a promise of a base64 encoded data URI

Usage
import ImageCharts from 'image-charts';

const chart_url = ImageCharts()
.cht('bvg') // vertical bar chart
.chs('300x300') // 300px x 300px
.chd('a:60,40') // 2 data points: 60 and 40
.toDataURI(); // download chart image and generate a data URI string

console.log(chart_url); // "data:image/png;base64,iVBORw0KGgo...

Enterprise Support

Image-Charts Enterprise and Enterprise+ subscriptions remove the watermark and enable advanced features like custom-domain, high-resolution charts, custom fonts, multiple axis and mixed charts.

Usage

Once subscribed to a plan you will receive an ACCOUNT_ID and a SECRET_KEY. These two parameters are mandatory to sign your request and remove the watermark. Replace both values in the code example below:

import ImageCharts from 'image-charts';

const chart_url = ImageCharts({secret: 'SECRET_KEY'})
.icac('ACCOUNT_ID')
.cht('p3') // pie chart
.chs('700x190') // 700px x 190px
.chd('t:60,40') // 2 data points: 60 and 40
.chl('Hello|World') // 1 label per pie slice : "Hello" and "World"
.chf('ps0-0,lg,45,ffeb3b,0.2,f44336,1|ps0-1,lg,45,8bc34a,0.2,009688,1') // 1 gradient per pie slice
.icretina('1') // enable paid-only features like high-resolution charts
.toURL(); // get the whole (HMAC signed) URL

console.log(chart_url);
// https://image-charts.com/chart?chd=t%3A60%2C40&chf=ps0-0%2Clg%2C45%2Cffeb3b%2C0.2%2Cf44336%2C1%7Cps0-1%2Clg%2C45%2C8bc34a%2C0.2%2C009688%2C1&chl=Hello%7CWorld&chs=700x190&cht=p3&icac=documentation&icretina=1&ichm=122242bb700d825d69b3fafe4ec67193b45dcfe0ed93fcca307e0d0a84b73ea2
