This would be only per macro possible (don't worked in ajax-client) and needs to be triggered very often. It's not recommeded to do such things, see Macros are Bad.
What is the aim for this? Maybe there are other ways.
I have two charts (Bar and PIE chart) in a container. On selecting one object(PIE Chart), I want few selections to be enabled. Is there any other way to do this?
I think in this case it's easier to use a button to switch per variable the object-visibilty between both objects. If you used two buttons and a frame you could it layout like a container.
