toFile(file) : Promise<()>Creates a file containing generated chart image and yield a promise.
When
fileis a filename, asynchronously writes data to the file, replacing the file if it already exists. Whenfileis a file descriptor, the behavior is similar to calling fs.write() directly (which is recommended).

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.
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 ChartJSImage from 'chart.js-image';
const ChartJSImage = require('..');
const chart_url = ChartJSImage({secret: process.env.SECRET_KEY || 'SECRET_KEY'})
.icac(process.env.ACCOUNT_ID || 'ACCOUNT_ID')
