you might also want to delegate the rendering to something else like https://image-charts.com or https://developers.google.com/chart/image/ :) – FGRibreau Jul 14 '19 at 08:00

There are a couple approaches. If it were me, I'd just create a rest JSON service that returned the raw data, then render it with jqplot on the client side.
Edit - If you need to create a PNG, then I might use: npmjs.com/package/nchart

Ah, you need to use something like nchart then, to create a png. For example: https://www.npmjs.com/package/nchart – Kevin Seifert Aug 12 '15 at 21:00
