While the odbxx API has been successfully used since the last months, a potential
problem with large ODBs surfaced. If you have lots of data in the ODB and load it
into an object like

After some thought, I changed the API again and removed the flag in the constructor,
so the system now automatically choses the best algorithm depending if the client

The problem lies in your function mhistory_init_one() in Mudas.js:1965. You can only call "new MhistoryGraph(e)" with an element "e" which is something

08 Feb 2023, Stefan Ritt, Suggestion, histories capture 'ruy'

> The histories capture key events from 'r' 'u' 'y' and 'Escape' for various functions like rescaling etc. However, this also means that if we include an
