The trial is a fully functional and feature complete version of Highcharts/Highstock for ASP.NET MVC that expires after 30 days of usage. The licensed version of Highcharts/Highstock for ASP.NET MVC is identical in every way to the trial with the exception that it never expires. The only thing that is needed to replace the Trial with Licensed version is to add serial key to Web.config file into appSettingsĀ section with key="Highcharts". Example: <add key="Highcharts" value="PlaceForSerialKey"/>.
