NEW Database
Create New Database after a certain period of time if plot web or desktop charts take a much longer time than at first usage.
It can be after a couple of months or even years, depends on Arduino Devices number in Arduino Control Center, enabled components for writing measurement and status data to database, a defined interval for writing to the database.
It means, that the size of the database becomes an issue for fast charts plotting.
Go to Tools -->NEW Database, you be prompted to close application and Database Manager window will show up.
As you can see on the image, all data except measurement data will be replicated(the old database will be renamed and saved, not deleted!).
Database size will be reduced, data for enabled components in charts will be starting from this date and time.
