Salvo	Hi, I would like to rspresent the history of a value through a web page. How can I take these values? Does hdb ++ have a rest API? I must use Tango Rest API and what parameters should I use? Should I connect to database directly? I couldn't find anything. Thanks, Salvo

Hi Salvo, As far as I know, HDB++ does not have yet a REST API. I know someone at the ESRF who developed something to display historic values from a set of attributes on a web page. I think it is currently connecting to the database directly. Kind regards, Reynald Rosenberg's Law: Software is easy to make, except when you want it to do something new. Corollary: The only software that's worth making is software that does something new.
