RequestChangeMetadata: function (sender, args);
sender. Event source.
args. Event information.
The RequestChangeMetadata event occurs on request to change series hierarchy metadata.
To execute the example, create a service for working with time series, create a component that will show hierarchy of time series database named maTree (see MetaAttributeTree Constructor), and add the following code in the <SCRIPT> tag:
maTree.RequestChangeMetadata.add(function(sender, args){console.log("Hierarchy metadata change")})
After executing the example on changing filter option (context menu item of the Hide time series) the RequestChangeMetadata event is fired, the browser console displays an appropriate message.
