        /*
         * Request timeout (in millisecond) when calling toBuffer() or toDataURI()
         */
        timeout: 5000,
    
        /*
         * (Enterprise and Enterprise+ subscription only) SECRET_KEY
         */

    }

    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
