Does HighChartsAPI Add-on uses Vaadin charts? if so… there is an alternative to create charts in vaadin? right now we can’t afford the vaadin pro tools.
It is easy check these kind of things by investigating projects pom.xml file(s). In this case there is no dependency to Vaadin Charts. However, note HighCharts itself is commercial product with its own terms and conditions, and licensing policy.

ok thank you, I will check HighCharts policies. I did check the project POM.xml and didnt find nothing of the vaadin charts, but I get worried because I receive a email from Vaadin saying that I have 2 weeks left from the vaadin charts try out period, but I haven’t downloaded to my project, so I was confused.
