I would like to use something like the following expression in a EasyChart cell update binding to hide one of the pens depending on which dropdown list item is selected -

Column: HIDDEN  
Value: if ({Root Container.Dropdown.selectedValue}\<22,1,0)

However, it seems that expressions are not allowed in cell update bindings…  
Any ideas how to accomplish this?

You could try putting your expression in a custom property for the Root Container and then reference just that property:

{Root Container.showColumn}

Is it possible to use indirect tags in cell bindings?

For a template where the tagpath is drop target (UDT).

{TagPath}+"/my tag name"
