I wanna make some charts, and I can make a little simple one, which generated by cuba and amCharts, but as I was reading the Add-Ons documentation, I saw a Chart Template Editor which one I glad if I could use, but I do not find it in Reports ? Show Charts. Here is that documentation: https://doc.cuba-platform.com/reporting-latest/template_chart.html
And I attached a file, what can I see there.
Could you help me where can I find that? And where can I find those chart’s xmls, and .java files?
