Accept chart settings and data and return a PNG of the chart
Create a service similar to https://pdfcrowd.com/.
Create an API endpoint that can convert settings into a file format (PNG) that is charged either per conversion or annually.
The API would take our chart settings and chart data, plot the chart on your server side and return to the client a PNG (or other supported file types) of the chart we requested.
Thank you for your suggestion!
Currently, you can use our public export server to do this. It runs at https://export.highcharts.com and accepts parateters as described at https://www.npmjs.com/package/highcharts-export-server.
There is however a limitation of 10 charts a minute. We are considering setting up a commercial service to allow more conversions.
The technical support also pointed us to the public export server but we would love a commercial service that did not have a rate limit.
