1.8. Replacing AmCharts Version
An instance of AmCharts library included in CUBA platform can be replaced with another one. To do this:
-  
Download charts and stock charts from AmCharts site.
 -  
Merge
amchartsfolder from both archives into one. -  
Copy
amchartsfolder to{project.rootDir}/modules/web/web/VAADIN/webjars -  
Redeploy the application.
 
To use new attributes added in a new version you need to set custom JSON in your screen controller as shown below.
chart.setNativeJson("{\"valueScrollbar\":{\"autoGridCount\":true}}");
