    Remove attributes from PI Vision symbol


      Hi All,


      I am working on some PI Vision symbols for a customer and I have a need to be able to remove attributes that I have associated with the symbol.


      For example I have a DataShape: 'Table'  symbol that I created by dragging across three attributes when creating it on a Vision page. From then on the 'data; object in the onDataUpdate contains a 'Rows' array with three objects, one for each attribute on the symbol. Now what I want to do is allow the user to remove some of the attributes. I can add them no problems by dragging them onto the symbol but is there a call to delete a specific one? I need to this for usability and ease of configuration for our end users... I know the standard trend has a button to remove traces (well, all but the last one!). See pic below. Is there something behind that that extension devs can call to remove an attribute?
