Hi there,
we are currently struggling with the Vaadin Charts for Flow - especially the export functionalities: While displaying the charts works pretty well and quite easy, we cannot manage to export them without internet access (which is not available in our production environment).
Investigation shows, that the Highcharts module “offline-export” is not included in Vaadin Charts, thus it always uses its fallback and tries to connect to the Highcharts servers. We followed this documentation here: https://www.highcharts.com/docs/export-module/client-side-export
How can we work around this issue and download a chart w/o internet access? The download format itself does not matter, we are fine with PDF as well as simple JPEG/PNG.
Thanks for your help and greetings from Germany!
